can you help me with this math problem?

Question

3-4x-3=-10x+7+2x+5(1-x)

and

-[-(-6)^2] + (-3)(-4)

Answer 1

....3 - 4x - 3 = -10x + 7 + 2x + 5(1 - x)
=>3 - 4x - 3 = -10x + 7 + 2x + 5 - 5x
----------o------ = --o-------------o-----------o
=>.....-4x.......+10x...........-2x........+5x = -3 +3 +7 +5
=> 9x = 12
=> x = 4/3

-------------------------------------------------------------------------------

......-[-(-6)²] + (-3)(-4)
.........___................
=> -[-36] + (-3)(-4)
....._____...............
=> 36 + (-3)(-4)
.............|....|.....
=> 36 + (+12)
=> 48

Answer 2

Are you sure you've written these correctly?

3-4x-3=-10x+7+2x+5(1-x)

Expand:
3-4x-3=-10x+7+2x+5-5x

Now collect terms. On the left side, the 3 and the -3 cancel.
On the right, the -10x, 2x and -5x can be added. Likewise, the 7 and the 5 can be added. This gives:
-4x = -13x + 12
Now move things so you've got a factor of x on one side and a constant on the other:

-4x +13x = -13x + 12 +13x
9x = 12
x = 12/9 = 1 1/3 = 1.3333 (repeat)

____
The other problem is what, just to evaluate the expression? Follow the rules: parentheses, powers, signs, multiplication, addition:

-[-(-6)^2] + (-3)(-4) =
-[-(36)] + 12 =
36 + 12 =
48

Answer 3

Well let's look at the first equation. 3 - 3 is zero and 5(1-x) = 5-5x Now we are left with -4x = -10x +7 +2x +5 -5x

Next transpose everything with x to the same side of the eqn. and we get 10x-2x+5x-4x = 7 +5

or 9x = 12 or x= 12/9 or 4/3

In the next expression -(-6)^2 = -36 and (-3)(-4)=12

finally -(-36)+12 = 36 +12 = 48

Hope this helps you a little. Remember your rules for signs and transposing from one side of an equation to the other and you should have no problem

Answer 4

(a.)
3 - 4x - 3 = -10x + 7 + 2x + 5(1 - x)
3 - 4x -3 = -10x + 7 + 2x + 5 - 5x
-4x +10x + 5x - 2x = 7 + 5 - 3 + 3
9x = 12
x = 12/9
x = 1.33

(b.)
-[-(-6)^2] + (-3)(-4) = -36 + 12 = -24

Answer 5

3-4x-3=-10x+7+2x+5(1-x)

-4x = -10x+7+2x+5-5x

-4x = -13x+12
Move -13x to the left side, which turns it positive. Positive 13 and negative 4 give you 9x

So:

9x = 12
Divide to get rid of the 9 on the left side and you get:
x = 12/9 or x = 1.333(repeating).


-[-(6)^2] + (-3)(-4)

-[-1(6)^2] + 12

Do exponents first on the left side:
-[-1(36)] + 12

now multiply whats inside the brackets:

-[-36] + 12

now distribute the -1 outside the bracket:
[36] + 12

Your answer is then 36 + 12
or, 48

Answer 6

The first equation simplifies to
-4x = -13x +12
Adding 13x to both sides then gives
9x = 12
Dividing both sides by 9 gives
x = 12/9
Simplifying the right side gives
x = 4/3

In the second expression, the first two -'s cancel each other, and so do the last two, so the expression is the same as
[(-6)^2)] + 3x4
For the forst part, -6 square dis 36. For the second, 3x=4=12. Hence the expression simplifies to
36 + 12
which evaluates to
48

Answer 7

-4x = -8x + 7 + 5(1-x)
-4x = -8x + 7 + 5 - 5x
-4x = -13x + 12
9x = 12
x = 12/9 = 4/3 = 1 1/3

(-6)^2 + 12
36 + 12
48

Answer 8

for the top equation: -4x=-3x+12
therefore, x=-12.

Answer 9

3-4x-3=-10x+7+2x+5(1-x)
3-3-4x=-10x+2x+7+5-5x
0-4x=-10x+2x-5x+7+5
-4x=-13x+12
13x-4x=12
9x=12
x=4/3


-[-(-6)^2]+(-3)(-4)
=-[-(36)]+12
=-[-36]+12
=36+12
=48
