polet [3.4K]4 years ago
6 0

Answer:

x = 15/2 or x = 7.5

Step-by-step explanation:

Step 1: Write equation

3(x + 4) = 7x - 18

Step 2: Solve for <em>x</em>

<u>Distribute 3:</u> 3x + 12 = 7x - 18

<u>Subtract 3x on both sides:</u> 12 = 4x - 18

<u>Add 18 on both sides:</u> 30 = 4x

<u>Divide both sides by 4:</u> x = 15/2 or x = 7.5
