x = 3y + 4
3x - 5y = 8
Because we have a value for x, we can plug it into the second equation to solve for y.
3(3y + 4) - 5y = 8
9y + 12 - 5y =8
Combine like terms.
4y + 12 = 8
Subtract 12 from both sides.
4y = -4
Divide both sides by 4.
y = -1
Because we have a constant value for y, we can solve for x.
x = 3(-1) + 4
x = -3 + 4
x = 1
The value of x is equal to 1.
The value of y is equal to -1.
