Question

Solve each variable. Then match each equation with its correct answer. х -7 -15 = b - 18 4=n-2 b-(-16) = 17​

Answer 1

PLEASE READ EXPLANATION

1.
`x = 7`

2.
`b = 3`

3.
`n = 6`

4.
`b = 1`

Explanation:

I’m going to assume the equations are as following - you made it a bit hard to read.

`x - 7 = 0`

`-15 = b - 18`

`4 = n-2`

`b-(-16) = 17`

I’m just shooting guesses here, if I said an equation wrong PLEASE let me know.

We can solve each equation by isolating x on one side.

Number 1:

`x - 7 = 0\\\\x - 7 + 7 = 0 + 7\\\\x = 7`

Number 2:

`-15 = b - 18\\\\-15 + 18 = b - 18 + 18\\\\3 = b`

Number 3:

`4 = n-2\\\\4 + 2 = n - 2 + 2\\\\n = 6`

Number 4:

`b-(-16) = 17\\\\b+16=17\\\\b + 16 - 16 = 17 - 16\\\\b = 1`

Hope this helped!
