Answer:

Subtract four on both sides.

Step-by-step explanation:

When we solve for x, we do the reverse of PEMDAS. The last letter is S, so we subtract. There is no subtraction, so we move to A for addition. There is addition, the plus 4, so to get rid of it, we subtract 4 on each side.

Answer: Subtract 4 from both sides of the equation.

Step-by-step explanation: In algebra, the equal sign separates and equation. 20 is a separate part. You would take the +4 and subtract it from itself and then also subtract 4 from the 20 which would give you 3x=16
