Oh, dude, 7y in math is just like saying "7 times y." It's like when you have 7 slices of pizza and y represents how hungry you are. So, if y is 2, you'd need 14 slices to satisfy your hunger. Math can be deliciously confusing, right?
7y = 3y - 12 4y = -12 y = -3
y=-9 7y-2=14y+61 7y-2-7y=14y+61-7y -2=7y+61 -2-61=7y+61-61 -63=7y -63/7=7y/7 -9=y
Yx7y = 7y2 (squared )
If you mean: (2x-7y)(x+y) then it is 2x squared -5xy -7y squared
y^2 + 7y + 12 = (y+4)(y+3)
x + 7y = 7 ⇒ 7y = -x + 7 ⇒ y = -x/7 + 1 ⇒ y intercept is 1.
y2+7y=18 y2+7y-18=0 (y+9)(y-2)=0 y=-9 & y=2
Well, honey, if 7y + 8 is equal to 57, then you just need to do a little math dance to solve for y. Subtract 8 from both sides to get 7y = 49, then divide by 7 to find y = 7. So, if 7y + 8 equals 57, then 2y would be 14. Hope that clears things up for ya!
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.
x = 7y x/7 = y
7y + 18 = 39 Therefore, 7y = 39 - 18 = 21 y = 21/7 y = 3
