Solve 9(t-1)-2(2t+3)-5(t+3)

$$9 ( t - 1 ) - 2 ( 2 t + 3 ) - 5 ( t + 3 )$$

Evaluate

$$-30$$

Solution Steps

Use the distributive property to multiply 9 by t-1.

$$9t-9-2\left(2t+3\right)-5\left(t+3\right)$$

Use the distributive property to multiply -2 by 2t+3.

$$9t-9-4t-6-5\left(t+3\right)$$

Combine 9t and -4t to get 5t.

$$5t-9-6-5\left(t+3\right)$$

Subtract 6 from -9 to get -15.

$$5t-15-5\left(t+3\right)$$

Use the distributive property to multiply -5 by t+3.

$$5t-15-5t-15$$

Combine 5t and -5t to get 0.

$$-15-15$$

Subtract 15 from -15 to get -30.

$$-30$$

Factor

$$-30$$
