Answer: x = 11
Step-by-step explanation:
<u>Given</u>
4 (x - 1) = 2 (x + 9)
<u>Expand parentheses and apply the distributive property</u>
4x - 4 = 2x + 18
<u>Subtract 2x on both sides</u>
4x - 4 - 2x = 2x + 18 - 2x
2x - 4 = 18
<u>Add 4 on both sides</u>
2x - 4 + 4 = 18 + 4
2x = 22
<u>Divide 2 on both sides</u>
2x / 2 = 22 / 2
