♡ The Explanation/Step-By-Step ♡

-  -4 (x + 5) - 9 = -45

Add 9 to both sides! This makes:

-4 (x + 5) - 9 + 9 = -45 + 9

Simplify!

-4(x + 5) = -36

Divide both sides by -4! This makes:

-4(x + 5) over -4 = -36/-4

Simplify!

x + 5 = 9

Subtract 5 from both sides! This makes:

x + 5 - 5 = 9 - 5

Simplify

x = 4

If x = 4..

-4 (4 + 5) - 9 = -45

-4(4 + 5) - 9

4(4 + 5) = 36

= -36 -9

Subtract the numbers: -36 -9 = -45!

= -45

Answer 2

Answer:

x=4

Step-by-step explanation:

Add 99 to both sides.

-4(x+5)=-45+9−4(x+5)=−45+9

Simplify  -45+9−45+9  to  -36−36.

-4(x+5)=-36−4(x+5)=−36

Divide both sides by -4−4.

x+5=\frac{-36}{-4}x+5=

​−4

​​−36

​​  

Two negatives make a positive.

x+5=\frac{36}{4}x+5=

​4

​

​36

​​  

Simplify  \frac{36}{4}

​4

​

​36

​​   to  99.

x+5=9x+5=9

Subtract 55 from both sides.

x=9-5x=9−5

Simplify  9-59−5  to  44.

x=4
