-8x - 10 - 20 = -8x - 30
8x + -2 = 10 8x = 12 x = 1.5
Y-8x plus 9y equals 10y-8x.
8x + 10 = 3x +145x = 4x = 4/5 = 0.8Improved answer:8x+10 = 4x+148x-4x = 14-104x = 4x = 1
x = -8, y = 10
f(x)= (4 - 5y)/8 f(y)= (4 - 8x)/5

3x+5y+8x+2y combine 3x and 8x to get 11x 11x+5y+2y combine 5y and 2y 11x+7y is the answer.
-8x - 10 - 20 = -8x - 30
The lines intersect at (3, 5)

8x + -2 = 10 8x = 12 x = 1.5
If you mean 8x+5y = 100 then it is a straight line equation
-8x-5y-45 is not an equation. An equation requires an equal sign in there somewhere. If you meant -8x-5y=45, then there are many ways to rewrite it, such as -(8x+5y)=45, or 8x+5y=-45, or 8x=-(45+5y), to name three. If you meant -8x-5y=-45, then you're probably looking for 8x+5y=45.
8x + 20y
The given expressions are: 5x + 5y = 30 3x - 5y = -30 Combine both equations to get: 5x + 3x + 5y - 5y = -30 + 30 8x = 0 Then: 8x/8 = 0/8 x = 0 Substitute that value for either of the expressions to get: 5(0) + 5y = 30 5y = 30 y = 30/5 y = 6 Therefore, the coordinates are x = 0 and y = 6.
