Question

Subtracting linear expressions 30 points

Answer 1

1. -2a + 2

2. x + 1

3. -5x + 5

Answer 2

1) -2a + 2

2) x + 1

3) -5x + 5

Step-by-step explanation(1):

`\left(7a+4\right)-\left(9a+2\right)\\=7a+4-\left(9a+2\right)\\=7a+4-9a-2\\=7a-9a+4-2\\=-2a+4-2\\=-2a+2`

Step-by-step explanation(2):

`\left(2x+5\right)-\left(x+4\right)\\=2x+5-\left(x+4\right)\\=2x+5-x-4\\=2x-x+5-4\\=x+5-4\\=x+1`

Step-by-step explanation(3):

`\left(2x+4\right)-\left(7x-1\right)\\=2x+4-\left(7x-1\right)\\=2x+4-7x+1\\=2x-7x+4+1\\=-5x+4+1\\=-5x+5`
