Question

6x+2y=12 how do I show my work

Answer 1

divide both sides
3x+y-6=0
move variable
6x=12-2y
divide
x=2-1/3y
solve
Final answer:
x=2

Answer 2

x=1 y=3

Explanation: I knew that 6+6 would equal 12, so I decided to make the 2 in the equation into a 6 by plugging in 3 to y. Then, I plugged in one to make it stay a 6. To check my work, 6(1)+2(3)=12
