How do you solve for x in #2x + 7 - 14 = 3x#?

Answer 1

Abigail Allen

#x=-7#

Considering that

#2x+7-14=3x#

#2x-7=3x#

#2x-7-3x=0#

#-x-7=0#

#x=-7#

#x=-7#

To get started, we can simplify our terms on the right.

#2x-7=3x#

Next, subtract #2x# from both sides to get

#-7=x#, or #x=-7#

I hope this is useful.

To solve for x in the equation 2x + 7 - 14 = 3x, you would first combine like terms to simplify the equation. So, you would combine 7 and -14 to get -7. Then, you would subtract 3x from both sides to isolate x. After simplifying, you would have -7 = x, which can be rewritten as x = -7. Therefore, the solution for x is -7.
