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

snow_tiger [21]

Answer:

PLEASE READ EXPLANATION

1. $x = 7$

2. $b = 3$

3. $n = 6$

4. $b = 1$

Step-by-step 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!

How many solutions are there to the equation below? 4(x-5)=4x-24

Mariana [72]

It is a linear equation so there can be 1 solution, 0 solutions, or infinite solutions

4(x-5)=4x-24

distribute

4x -20 = 4x-24

subtract 4x from each side

-20 = -24

no solutions
