Answer:

PLEASE READ EXPLANATION

1. [tex]x = 7[/tex]

2. [tex]b = 3[/tex]

3. [tex]n = 6[/tex]

4. [tex]b = 1[/tex]

Step-by-step explanation:

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

[tex]x - 7 = 0[/tex]

[tex]-15 = b - 18[/tex]

[tex]4 = n-2[/tex]

[tex]b-(-16) = 17[/tex]

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:

[tex]x - 7 = 0\\\\x - 7 + 7 = 0 + 7\\\\x = 7[/tex]

Number 2:

[tex]-15 = b - 18\\\\-15 + 18 = b - 18 + 18\\\\3 = b[/tex]

Number 3:

[tex]4 = n-2\\\\4 + 2 = n - 2 + 2\\\\n = 6[/tex]

Number 4:

[tex]b-(-16) = 17\\\\b+16=17\\\\b + 16 - 16 = 17 - 16\\\\b = 1[/tex]

Hope this helped!
