Value of x: 2.5

Value of y: -0.5

-------------------------

To find x:

x + 1 = 3x - 4

-x -x

1 = 2x - 4

+4 +4

5 = 2x

-- ---

2 2

2.5 = x

Check:

2.5 + 1 = 3(2.5) - 4

3.5 = 7.5 - 4

3.5 = 3.5

To find y:

3y = 5y + 1

-5y -5y

-2y = 1

--- ----

-2 -2

y = -0.5

Check:

3(-0.5) = 5(-0.5) + 1

-1.5 = -2.5 + 1

-1.5 = -1.5
