Answer:
a = 1
Step-by-step explanation:
Step 1: Write equation
3(a - 1) + 2a = a + 1
Step 2: Solve for <em>a</em>
<u>Distribute 3:</u> 3a - 3 + 2a = a + 1
<u>Combine like terms:</u> 5a - 3 = a + 1
<u>Subtract a on both sides:</u> 4a - 3 = 1
<u>Add 3 on both sides:</u> 4a = 4
<u>Divide both sides by 4:</u> a = 1
