Answer:

5y+25= 30y

5y+5= 10y

8x-12= -4x

4x+24= 28x

Step-by-step explanation:

If you see a math problem with one variable (letters) and one a number by itself, the anwar will always be the variable after the number you had answar like for EXAMPLE: 1x+1= 2x

5y + 25 is y = 5 (opposite of multiplication is division, you have to do the opposite operation to isolate the variable which is in this case, y)

5y + 5 is y = 1 (5/5 = 1)

8x + 12 is x = 1.5 (21/8 = 1.5)

and 4x + 24 is x = 6 (24/4 = 6)
