For the following system, use the second equation to make a substitution for y in the first equation.
2x + y = 6
y = 3x + 4
What is the resulting equation?
y + 2x + y = 6
2x + y + 3x + 4 = 6
2x + (3x + 4) = 6
2x + y = 6
y = 3x + 4
What is the resulting equation?
y + 2x + y = 6
2x + y + 3x + 4 = 6
2x + (3x + 4) = 6
