13(y+7)=3(y-1)

13 (y + 7) = 3 (y - 1)

y = - \frac{47}{5}

Solution steps

13 (y + 7) = 3 (y - 1)

Expand

13 (y + 7) : 13 y + 91

Expand

3 (y - 1) : 3 y - 3

13 y + 91 = 3 y - 3

Move

91

to the right side

13 y = 3 y - 94

Move

3 y

to the left side

10 y = - 94

Divide both sides by

10

y = - \frac{47}{5}

4 x - 1 = 3 (x - 1)

x, 3 y - 3 x = 21

x, 2 x + 2 x y = 0

x, 5 x + 4 y = 10

\frac{2 x}{15} = \frac{4}{5}
