X=3y+4

3x-5y=8

Solve using substitution

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.
