Question

4 (-2×+9) = - 2 (3×-7)​

Answer 1

Explanation:

4(-2x + 9) = -2(3x -7) {use distributive rule}

4*-2x + 4*9 = -2*3x - 7*(-2)

-8x + 36 = -6x + 14

Subtract 36 from both sides

-8x + 36 - 36 = -6x + 14 -36

-8x = -6x - 22

Add 6x to both sides

-8x + 6x = -6x +6x - 22

-2x = -22

Divide both sides by (-2)

-2x/-2 = -22/-2

x = 11
