Best ResponseYou've already chosen the best response.0That's not the substitution method; that's subtraction. Because you solved them both to equal 2x+4x, you could substitute them by taking the righthand sides of both of the equations and setting them equal to each other:\[9y3=8y+3\]Then solve for y:\[9y=8y6\]\[y=6\]
