Answer:
Step-by-step explanation:
standard form is ax+b=0 that means the equation should be on the left side while the right side should always be 0
21. y+7=2 (move 2 to the left side) y+7-2=0 y+5=0
22. 2m=10 ... 2m-10=0
23. 5x + 3 ? im guessing there is a typo in the book here ? just write it 5x+3=0
24. 2y - 4 = y 2y-y-4=0 y-4=0
25. 5x+2 = 3 5x+2-3=0 5x-1=0
