Question

Soo-Jung used the subtraction property of equality to solve an equation for y. Which equation could be the one that Soo-Jung solved?
4 y = 12
y/4=12
2 (4 y) = 12
y + 4 = 12

Answer 1

thoughts? if he uses the *subtraction property of equality* that means he needs to subtract something from both sides to isolate the variable

so you should be looking for the **opposite** of subtraction in the original equation
