x = 5, y = -2
By elimination: x = 3 and y = 0
its 5 because if y is 3 then u have to ask yourself wat times 3 + 7 is 22
That equals 2xy + 3y which factors to y(2x + 3)

Solving by elimination: p = 3 and q = -2
Yes and it works out that x = 3 and y = 4
2xy + 6 = 4xyz Divide through by 2: xy + 3 = 2xyz 3 = 2xyz - xy = y*(2xz - x) Therefore, y = 3/(2xz - x) provided that 2xz - x is not zero.
-24, but dude, learn to do your homework
If you're solving for x, then x = 3/y.
the answer is x(3+y)
4xy+1=3y-7x 4xy-3y=-7x-1 y(4x-3)=-7x-1 y=(-7x-1)/(4x-3)
x + 8y = 3 therefore 2x + 16y = 6 (a) 2x + 3y = -7 (b) Subtract (b) from (a): 13y = 13 so y = 1 and x = -5
