Question

Solve the following step by step with explanation

4(-x+5)=40

-3(-4+x)= -16

2(2x+6)=20

Answer 1

Answer:

4(-x+5) = 5

=> -4x + 20 = 5

=> -4x = 5-20

=> -4x = -15

=> 4x = 15

=> x = 15/4

-3(-4+x) = -16

=> 12-3x = -16

=> -3x = -16-12

=> -3x = -28

=> 3x = 28

=> x = 28/3

=> x = 7

2(2x+6) = 20

=> 4x+12 = 20

=> 4x = 20-12

=> 4x = 8

=> x = 8/4

=> x = 2
