3y + 8 = 3 -8 -8 3y=-5 (3y)/3=-5/3 y=(-5/3)
Set it equal to 0 and subtract x and solve for y
y + 8 = 0 y = -8

7x + y = 4y = 4 - 7x
8
7x + y = 8 Subtract 7x from each side of the equation: y = -7x + 8
You can't solve it. But you can simplify it to get: 4x+y=2
x+xy=8 xy=-x+8 y=-1+8/x
y=4x-8y=2x+10Substitute (4x-8) for y in the second equation and solve for x:4x-8=2x+102x=18x=9Now solve for y:y=4(9)-8=28(9,28)
You cannot solve one linear equation in two variables. You can express y in terms of x but that is NOT solving for y.
y/2 + 8 = 13 Subtract 8 from both sides: y/2 = 5 Multiply both sides by 5: y = 10
5x+y=-7 3x+y=15 8=D
To find the y intercept put zero in for x and solve. To find the x intercept put zero in for y and solve. (0,8) and (-8,0)
5+(8*X) = Y You don't have enough info. to solve for Y.... I think. :)
-y + y equals 0.
