1 answer:
Answer:
x = 9
Step-by-step explanation:
Step 1: Write equation
4(x - 2) = 3x + 1
Step 2: Solve for <em>x</em>
<u>Distribute 4:</u> 4x - 8 = 3x + 1 <u>Subtract 3x on both sides:</u> x - 8 = 1 <u>Add 8 to both sides:</u> x = 9
Step 3: Check
<em>Plug in x to verify it's a solution.</em>
<u>Substitute:</u> 4(9 - 2) = 3(9) + 1 <u>Parenthesis (add):</u> 4(7) = 3(9) + 1 <u>Multiply:</u> 28 = 27 + 1 <u>Add:</u> 28 = 28
