Use elimination method:

3x-3y=5

2x+8y=11

Factor out the common term 33

3 (x-y) = 53 (x-y) = 5

2 Divide both sides by 33

x-y=/frac{5}{3}x-y=

3



5



3 Add yy to both sides

x=/frac{5}{3}+yx=

3



5

+ y

1 Factor out the common term 22

2 (x+4y) = 112 (x+4y) = 11

2 Divide both sides by 22

x+4y=/frac{11}{2}x+4y=

2



11



3 Subtract 4y4y from both sides

x=/frac{11}{2}-4yx=

2



11

- 4y
