Solve by substition 4x plus 3y equals 1 y equals 2x plus 8?

4x + 3y = 1y = 2x + 8

Take the first part:

4x + 3y = 1y

4x = 1y - 3y

4x = -2y

x = -y/2

Substitute x in second part:

1y = 2x + 8

1y = -2y/2 + 8

1y = -1y + 8

2y = 8

y = 4

Substitute y into either part:

1y = 2x + 8

1(4) = 2x + 8

4 - 8 = 2x

-4 = 2x

x = -2

Therefore:

x = -2

y = 4
