x is equals to 4 and y is equal to 1
Step-by-step explanation:
3x+3y=9
x-3y=7
elimination method has to do with eliminating one variable from the question to eliminate y we have to add the equations together which is 4x=16
X=4
substitute x is equal to 4 into any equation of your choice let's use equation 1
E
3(4)+3y=9
12+3y=9
12-9=3y
3=3y
divide both sides by 3 therefore y is equal to 1.
