x+3=2x+4 is true, what is the value of x to make this equation true?

Answer 1

x + 3 = 2x + 4

x - 11 = 2x

x = -1

Answer 2

x+3 = 2x + 4
x = 2x + 1
0 = x + 1
-1 = x

Answer 3

x+3 = 2x+4
x-2x = 4-3
-x = 1
x = -1

To check, substitute the value of x:
x+3 = 2x+4
(-1)+3 = 2(-1) + 4
2 = -2 +4
2 = 2
so x= -1 is correct :)

Answer 4

Okay, first remember that with equations whatever you do to one side of the equation, you have to do to the other side, to keep it equal.

Starting with your original equation,

X+3 = 2X+4

then subtract 4 from both sides

X - 1 = 2X

X = -1

Answer 5

you may first be sure the equation ignoring absolutely the fee signs and indications and then you may multiply the aspect without absolutely the fee signal by technique of -a million and be sure it that way again. (at the same time as multiplying by technique of -a million, no matter if that's a lower than / more effective than / lower than or equivalent to / more effective than or equivalent to equation you may opposite the signal from lower than to larger than and vise versa) a million. 3 <= x <= 5 . . . . . (assuming that on your question that's a lower than or equivalent to signal) (remember to modify the signal round once you multiply both aspect by technique of -a million to get the equation from -x <= -3 to x >= 3 ) 2. x = 2 , -6/5 3. x = 2 , -4/3

Answer 6

The answer is -1

Answer 7

x+3-3=2x+4-3
x=2x+1
x-2x=3x-2x+1
-x=1
-x/-1=1/-1
x=-1

Answer 8

3=x+4
x=-1
The correct answer is -1.

Answer 9

i got:
x=-1

always include the x, not just 1

-x=1
x=-1

Answer 10

answer: -1
