3(x + 4) = 7x - 18
How do I solve it?

x = 7.5

Step-by-step explanation:

Step 1:

3 ( x + 4 ) = 7x - 18           Equation

Step 2:

3x + 12 = 7x - 18        Multiply

Step 3:

12 = 4x - 18         Subtract 3x on both sides

Step 4:

30 = 4x         Add 18 on both sides

Step 5:

x = 30 ÷ 4         Divide

x = 7.5
