3. solve each system of equations by substitution. if there is exactly one
solution, check the solution.
a) 2x+y=6 c) x - 2y=4 e 2+3y=6 g) 2x - y = 13.
3x+2y=10 2x - 3y=7 x+y=3
x+2y=-6
i) 2x + 3y = 5 k) a + 4b = 3 m) 27-s=2
or - 4y = 8
2 - 4y=-14 56=-2a+3 3r-25=3
2x - 8y=8
q) x+y-4=0 s) 6x = 3y + 2 u) 3f=8-4
2x=8-2y y -2x+4=0 28=f+3.
