75=3(-10t-3)+6t

75 = 3 (- 10 t - 3) + 6 t

t = - \frac{7}{2}

Solution steps

75 = 3 (- 10 t - 3) + 6 t

Switch sides

3 (- 10 t - 3) + 6 t = 75

Expand

3 (- 10 t - 3) + 6 t : - 24 t - 9

- 24 t - 9 = 75

Move

9

to the right side

- 24 t = 84

Divide both sides by

- 24

t = - \frac{7}{2}

9 m = - 63

- 6 x + 3 = - 9

5 x - 3 = x + 9

2 y - 3 = 4 y + 6

- 2 x + 8 = - x + 7 - x + 7
