6-2 Substitution
The solution is (0, 2).
3x + y = 6
4x + 2y = 8
3x + y = 6
4x + 2y = 8
First, solve the first equation for y to get y = 3x + 6. Then substitute 3x + 6 for y in the second equation.
Use the solution for x and either equation to find y.
The solution is (2, 0).
2x + 3y = 4
4x + 6y = 9
2x + 3y = 4
4x + 6y = 9
First, solve the first equation for x.
Then substitute
for x in the second equation.
