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

X+3y=5-2x-6y=-10Solve using elimination

X+3y=5

-2x-6y=-10
