Question

Solve the following linear equation
7(x - 2) = 4(x + 1) - 21

Answer 1

7(x-2)=4(x+1)-21 perform indicated multiplications on both sides

7x-14=4x+4-21 combine like terms on right side

7x-14=4x-17 add 14 to both sides

7x=4x-3 subtract 4x from both sides

3x=-3 divide both sides by 3

x=-1
