Answer: 4x+13



Solution Steps

2(5x+3×2−4)−(6x−9)

Multiply 3 and 2 to get 6.

2(5x+6−4)−(6x−9)

Subtract 4 from 6 to get 2.

2(5x+2)−(6x−9)

Use the distributive property to multiply 2 by 5x+2.

10x+4−(6x−9)

To find the opposite of 6x−9, find the opposite of each term.

10x+4−6x−(−9)

The opposite of −9 is 9.

10x+4−6x+9

Combine 10x and −6x to get 4x.

4x+4+9

Add 4 and 9 to get 13.

4x+13
