31 - 12 = x

Hope this helped thanks.

Answer 2

Melody added 12 to both sides when she should've subtracted 12 from both sides.

X = 19

Explanation:

When solving equations, you have to do the opposite operation given on both sides of the equation. In this case, the operation that's happening is addition, so we have to subtract 12 from both sides.

Step 1: Subtract 12 from both sides.

• 
  `x+12-12=31-12`
• 
  `x = 19`
