Slimination
multiply first equaiton by 2
2x+6y=10
add to second equiaotn
2x-2x+6y-6y=10-10
0=0
this is true so therfor they are the same equaiton
so solve
x+3y=5
3y=-x+5
y=-1/3x+5/3
subsituter values for x and get valuse for y
if x=2 then y=1
Answer:
Yeah
Step-by-step explanation:
Answer: let's say x = 1
16 x 1 =16
16+20=36
36x1/2=18
