my question is this how do you solve this equation?
x=3y-1
x+2y=9
solve each system of equation by the substitution method.

• algebra -

Substitute 3y -1 for x in the second equation, and solve the resulting equation for y

3y -1 + 2y = 9
5y = 10
Take it from there

• algebra -

(3y-1) + 2y = 9
5y - 1 = 9
5y = 10
y=2

x=3(2)-1
x=5

(5,2)
