Answer:
It is not correct, the answer is 15
Step-by-step explanation:
They forgot the rule of PEMDAS, and accidentally subtracted before they multiplied. It should've gone
(25+3) - 7 x 3 + (2x4)
28-7x3+8
28-21+8
Since it's minus 21, that means it's negative, so -21+8=13
28-13=15
7y +8= 9+3y+2y
Combine like terms.
7y+8= 9+5y
Subtract 5y on both sides.
2y+8=9
Subtract 8 on both sides.
2y=1
Your answer is 2y=1
I hope this helps!
