Answer:

12

Step-by-step explanation:

7y-5y+12=20+2y+4(combine and subtract 7-5)

2y+12=20+2y+4

2y+12=24+2y(add)

2y+12=2y+24(flip 24+2y into: 2y+24)

2y+12-12=2y+24-12(subtract 12 from both sides)

2y=2y+12(simplify, subtract them)

2y-2y=2y+12-2y(subtract 2y from both sides)

0=12(simplify terms)

Hope this helps! If so, make me brainliest please! Thanks!
