Answer:

3x − 49

Step-by-step explanation:

Replace all occurrences of ++−- with a single −. A plus sign followed by a minus sign has the same mathematical meaning as a single minus sign because 1⋅−1=−1

1 + 5(3x − 10) − 12x

Apply the distributive property.

1 + 5(3x) + 5 x −10 − 12x

Multiply 3 by 5.

1 + 15x + 5 x −10 − 12x

Multiply 5 by −10.

1 + 15x − 50 − 12x

Simplify by adding terms

Subtract 50 from 1.

15x − 49 − 12x

Subtract 12x from 15x.

Answer: 3x − 49

Answer:

The answer is 3x − 49
