How would you solve 5x-y equals 5 and 2x-y equals 1 using subsitution?

When solved by substitution: x = 4/3 and y = 5/3
From equation 2, y = 2x - 1
Substituting this expression for y in equation 1 gives 5x -(2x - 1) = 5
this simplifies to 3x + 1 = 5 making x = 4/3 and y = 5/3

How do you solve mathematical equations using the subsitution method?
Say you have a pair of equations like a+b=1 and 2a+3b=5. To solve using substitution you would set one equation against one variable (say a=1-b) then plug that into the other (2(1-b)+3b=5), then solve for the one variable you have there and then plug that result into the other equation (in this case b=3 and a=-2).
