Question

What is the solution of this equation?

2x +x-11+3-7x=15


A. X=7/4

B. X=-7/4

C. X=-23/4

Dx=23/4

Answer 1

To solve the equation 2x + x - 11 + 3 - 7x = 15, let's simplify it step by step:

Combining like terms, we have:
2x + x - 11 + 3 - 7x = 15
(2x + x - 7x) + (-11 + 3) = 15
-4x - 8 = 15

Next, let's isolate the variable x:
-4x - 8 + 8 = 15 + 8
-4x = 23

To solve for x, we divide both sides of the equation by -4:
(-4x) / -4 = 23 / -4
x = -23/4

Therefore, the solution to the equation is:
C. x = -23/4.
