Question

solve equation and check results 5x +7 =2x-8​

Answer 1

5x + 7 = 2x - 8

5x - 2x = -8 - 7

3x = -15

x = -5

putting the value of x in 5x + 7 = 2x - 8

LHS:

5(-5) + 7

-25 + 7

-18

RHS:

2(-5) - 8

-10 - 8

-18

LHS = RHS

Answer 2

Answer:

-5

Step-by-step explanation:

5x + 7 = 2x-8

5x -2x = -8 -7

3x = -15

x = -15/3

x = - 5

now putting value of x

5x + 7 = 2x - 8

5 x (-5) + 7 = 2 x (-5) - 8

- 25 + 7 = -10 - 8

- 18 = -18
