Y = 9
7y - 10y = -3y
bring down the 9 = -18 so
-3y + 9 = -18
9 - 9 = 0
- 18 - 9 = - 27
- 3y ÷ - 3 = y
- 27 ÷ -3 = 9
therefore y =9
Tip:

Answer:
S = 1564
Step-by-step explanation:
S = 12 + 22 + 32 + .. + 172
= 12 + (12+10) + (12+20) + .. + (12+160)
= 10(1 + 2 + .. + 16) + 12×17
= 10×16×17/2 + 12×17
= 1360 + 204
= 1564
X= -2
25x+30= -22 -x
*subtract 30 from -22*
25x= -52
*divide 25 from each side*
x= -2
