what's 10-3x = 2x-8x + 40?

Question

I'm having trouble working out problems with 3 like terms could someone one help me?

Answer 1

10-3x=2x-8x+40
10-3x=-6x+40
10+3x=40
3x=30
x=10
:)

Answer 2

x = 10

Answer 3

x = 10

Answer 4

x=10

Answer 5

10- 3x = 2x - 8x + 40
take all like terms on one side
-3x - 2x + 8x = 40 - 10
+ 3x = 30
x = 30 / 3
x = 10

Answer 6

10-3x=2x-8x+40

so first, look at both sides and combine like terms.
the left side has no like terms so for now, leave it alone.
the right side, on the other hand, has 2x-8x, so we can combine this to be -6x
our new equation looks like this:

10-3x=-6x+40

now, add the -6x to both sides, so it cancels on the right side, and it adds to the left side to produce the following:

10-3x=40

now, subtract 10 from either side, which will result in 0 on the left side and 30 on the right to give you:

-3x=30

now, divide both sides by -3, so you have an equation that is "x="

x=30/-3

now, simplify the equation to

x=-10

this is your answer, in a long-winded, step-by-step manner....you'll be fine if you can just remember to combine like terms before evaluating the rest of the problem.

Answer 7

Sure, this is pretty simple
10 - 3x = 2x - 8x + 40
10 - 3x = -6x + 40
-3x = -6x + 40 - 10
-3x = -6x + 30
-3x + 6x = 30
3x = 30
x = 30/3
x = 10

I hope that helped

Answer 8

first get all like terms on same side;

10-40=2X-8X+3X
or
2x+3x-8x=-30

5x-8x= -30
-3x= -30
multiply both sides by -1
3x=30
divide both sides by 3
x=10
if ya want plug 10 into orginal equation and the result shoud cancel out

Answer 9

= 10 - 3x = -6x + 50 (then add 6x to each side)
=10 + 3x = 50 (then subtract 10 from each side)
= 3x = 40
= x = 40/3 or 13.333333

Answer 10

10 - 3x = 2x - 8x + 40
-3x - 2x + 8x = 40 - 10
3x = 30
x = 10
