-1= 1/2 x+5

- 1 = \frac{1}{2} x + 5

x = - 12

Solution steps

- 1 = \frac{1}{2} x + 5

Switch sides

\frac{1}{2} x + 5 = - 1

Move

5

to the right side

\frac{1}{2} x = - 6

Multiply both sides by

2

x = - 12

3 x + 3 x + 6 = 5 x + 8 - x

9 x - x + 56 = 7 + 3 x - 1

\frac{x}{5} = \frac{4}{7}

u, 2 (3 v + 2 u) - 5 (u + 5 v) = - 2 u - 3 v

- \frac{x + 3}{2} - \frac{x}{4} = \frac{3}{2}
