Solve this system of equations using substitution. Check.
3y - 2x = 11
y + 2x = 9
The substitution method is used to eliminate one of the variables by
replacement when solving a system of equations.
Try to chose the variable with a coefficient of ONE.
Which variable should we solve for first?
Homework:
Solve each system of equations using the "substitution" method:
1)
2x + y = 1
y=3-x
2) 3x + y = 2
9x + 2y = 2
3) 2y = 6 - x
x + 2y = 6
4) 3x = y + 6
2y = 6x - 10
