<span>Clear out any fractions by Multiplying every term by the bottom parts.Add or Subtract the same value from both sides.Divide every term by the same nonzero value.Combine Like Terms.Factoring.<span>Expanding (the opposite of factoring) may also help.</span></span>
<span>1.First, write down the expression: 2.ex"</span><span>2a + 3 = 7. 3Then, undo the + 3 by subtracting Remember, you need to do it to BOTH sides! 5.2a + 3 - 3 = 7 - 3, 6.so 2a = 4. 7.Undo the multiply by 2 by dividing by 2, again on both sides:<span>2a ÷ 2 = 4 ÷ 2.</span></span>
