x + 7y = 7 ⇒ 7y = -x + 7 ⇒ y = -x/7 + 1 ⇒ y intercept is 1.
5y+8=7y 2y=8 y=4
This simplifies to 6+13y If you meant 9+7y-(3+6y) then it becomes 6+y It is not clear from the problem which you meant.

y-3x+6y=12 7y=3x+12 y=3x/7 +12/7
y^2 + 7y + 12 = (y+4)(y+3)
-7y = -91 divide both sides by -7 y = 13
x = 7y x/7 = y
x + 7y = 7 ⇒ 7y = -x + 7 ⇒ y = -x/7 + 1 ⇒ y intercept is 1.
-6y+3 = -7y+8 -6y+7y = 8-3 y = 5
(y + 5) (y + 2)
7y + 18 = 39 Therefore, 7y = 39 - 18 = 21 y = 21/7 y = 3
7y+3=y+18 Subtract three 7y=y+15 Subtract y 6y=15 Divide Y=15/6 That's your fraction if you need a decimal just type it in the calculator...
5y+8=7y 2y=8 y=4
7x + 8y
y2+7y=18 y2+7y-18=0 (y+9)(y-2)=0 y=-9 & y=2
