Question

Solve the equation 3(x+4.5)=36. If you get stuck, use the diagram.

Answer 1

x=7.5

Explanation:

Let's solve your equation step-by-step.

3(x+4.5)=36

Step 1: Simplify both sides of the equation.

3(x+4.5)=36

(3)(x)+(3)(4.5)=36(Distribute)

3x+13.5=36

Step 2: Subtract 13.5 from both sides.

3x+13.5−13.5=36−13.5

3x=22.5

Step 3: Divide both sides by 3.

3x/3=22.5/3

x=7.5

Answer:

x=7.5
