Substitution method you're taking one of the variables in one equation and change it within the different. Or, y = 3x + 2 in a single equation, so that you may simply plug the 3x + 2 into the opposite equation to clear up for x: 2x + y = 5 goes to 2x + (3x + 2) = 5 2x + 3x + 2 = 5x + 2 = 5 solve for x: 5x = 5 - 2 = three x = three/5 then you can put the worth you located for x into either equation to find y: y = 3x + 2 goes to y = 3 (three/5) + 2. Y = 9/5 + 2 y = 9/5 + 10/5 y = 19/5 so... X = three/5 and y = 19/5

Verified answer
6x – y = 1
Subtract 6x to each side.
-y = -6x + 1
Divide by -1.
y = 6x - 1
First choice.
Answer: y=6x-1.
