y+2x=40 => x=(40-y)/2 y=12 => x=(40-12)/2 => x=14

y+2x=40 y=12 ------------ 12+2x=40 2x=40-12 2x=28 x=28/2 x=14 Answer: 14

Substitute 12 + 2x = 40 Subtract '12' from both sides 2x = 28 Divide both sides by '2' x = 14

y=12 ---> 12+2x=40 solve for x

x = 14. Make the substitution for y, then solve for x as normal.

2x = 40 - 12 2x = 28 x = 14
