solve for

y, 2 x + 4 y - 31 = 123

y = \frac{- x + 77}{2}

Solution steps

2 x + 4 y - 31 = 123

Move

2 x

to the right side

4 y - 31 = 123 - 2 x

Move

31

to the right side

4 y = - 2 x + 154

Divide both sides by

4

y = \frac{- x + 77}{2}

y, 5 x + 2 y = 10

y, x - 2 y = 10

y, 3 x + y = 3

y, 3 x + y = 2

5 (2 z + 1) = 15
