Question

Simplify: 4(5x-1)-8x+11=?

Slove: -5(x+1)+3x=6-(4x-3)=?

Answer 1

• 4(5x - 1) - 8x + 11 = 12x + 7

• -5(x+1)+3x = 6-(4x-3) ↔ x = 7

Explanation:

4(5x - 1) - 8x + 11

= 20x - 4 - 8x +11

= 12x + 7

-5(x + 1) + 3x = 6 - (4x - 3)

↔ -5x - 5 + 3x = 6 - 4x + 3

↔ -2x - 5 = 9 - 4x

↔ 2x = 14

↔ x = 7

Answer 2

1. 12x+7

2. x=7

Explanation:

1. 4(5x-1)-8x+11=?

multiply 4(5x-1)

20x-4-8x+11

Subtract 8x from 20x which is 12x

then subtract 4 from 11 which is 7

12x+7
