I don't know. But I know how to find it. Let's work it out together:
<u>5x = 2x + 20</u>
Subtract 2x from each side: 3x = 20
Divide each side by 3 : <em>x = 20/3</em> or ( 6 and 2/3 ).
Answer:
x = 4
Step-by-step explanation:
Step 1: Write out equation
3x + 6 = 18
Step 2: Subtract 6 on both sides
3x = 12
Step 3: Divide both sides by 3
x = 4
