Solve the equation 3x = 24 for x = _________.

A 8

To isolate the unknown value x, we divide both sides of the equation by 3.
On the left, dividing by 3 “undoes” the effect of multiplying by 3 and returns to x. On the right, 24 ÷ 3 = 8. x=8
To check, substitute the solution 8 into the original equation.
Original equation: 3x = 24
Substitute 8 for x: 3(8)=24
Simplify both sides: 24=24
