Question

Solve the equation: x/2-18=(-28). What is x?

Answer 1

$\frac{x}{2} -18=-28$   Add 18 on both sides

$\frac{x}{2} -18+18=-28+18$

$\frac{x}{2}=-10$   Multiply 2 on both sides

$(2)\frac{x}{2} =-10(2)$

x = -20

[proof]

$\frac{x}{2} -18=-28$

$\frac{-20}{2}-18=-28$

-10 - 18 = -28

-28 = -28
