-9+7y+y=1-2y

- 9 + 7 y + y = 1 - 2 y

y = 1

Solution steps

- 9 + 7 y + y = 1 - 2 y

Add similar elements:

7 y + y = 8 y

- 9 + 8 y = 1 - 2 y

Move

9

to the right side

8 y = - 2 y + 10

Move

2 y

to the left side

10 y = 10

Divide both sides by

10

y = 1

2 y + 3 = (y + 1) 2

\frac{- 5 x + 2}{7} = - 4

15 = 5 - 2 x

1 - \frac{7}{5} = \frac{x + 3}{20}

y = - 5 (0) + 3
