Question

What is the solution to this equation?

2x+x-11+3-7x= 15:
OA. X=
23
4
B. x=
C. x =
74
7
4
D. x=-
*23/4

Answer 1

D. x = -23/4

Explanation:

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

Combine like terms

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

= -4x - 8 = 15

= - 4x = 15 + 8

= -4x = 23

= x = -23/4

Therefore x = -23/4

Answer 2

`2x+x-11+3-7x=15\\3x-8-7x=15\\-4x-8=15\\-4x=23\\x=-(23)/(4)`
