Solve each system of linear equation by substitution.

X+4y=6

Y=-X+3

Since one equation has a variable already solved for, we can use that to plug it in to the other equation.

Y has been solved for, plug it into the other one

x + 4 (-x+3) = 6

x + - 4x + 12 = 6

-12. - 12

x + (-4x) = - 6

-3x = - 6

/-3. / - 3

x=2

y = - x+3

y = - (2) + 3

y=1
