solving systems of equations algebraically (solving systems of equations by
substitution and elimination) assignment
solve the systems of equation by substitution method.
1. 2x + y = 1
x + y = 2
3x - y = 4
2x - y = 1
2.
3.
y=2x-3
3x + 2y = 8
4. y = 2x + 3
y = 5x - 3
2x – 1=1
5.
6a+b=4
5a + 2b = 1
x+4y+3=0
6.
2x-1=1
x+4y+3=0
7.
2x+y=7
2x-y=3
8.
2(x-y)=8
x+y=6
