-7w + 2(w + 8) = -24

First, expand your equation.
-7w + 2w + 16 = -24
Second, add '-7w + 2w' to get '5w'.
-5w + 16 = -24
Third, take away '16' from both sides.
-5w = -24 - 16
Fourth, subtract '-24 - 16' to get '-40'.
-5w = -40
Fifth, divide both sides by '-5' and change it into a positive.
w =  \frac{40}{5}
Sixth, how many times does 5 go into 40? 40 ÷ 5 = 8.
w = 8

Answer: w = 8

For each expression, write an equivalent expression that uses only addition.
konstantin123 [22]

Equivalent expressions are expressions of equal values

The equivalent expressions are 4x+ (y - 8y) + (2z-5z) +6   and 6x-3x-6x + (2y - 10y) + (4 - 8) + (z - 88z)

<h3>How to determine the equivalent expressions</h3>

The first expression has been solved.

So, we have the following expressions

4x−7y−5z+6 and -3x−8y−4−87z

<u>4x−7y−5z+6</u>

We have:

4x-7y-5z+6

Rewrite as:

4x+ (y - 8y) + (2z-5z) +6

<u>-3x−8y−4−87z</u>

We have:

-3x−8y−4−87z

Rewrite as:

3x-6x + (2y - 10y) + (4 - 8) + (z - 88z)

Hence, the equivalent expressions are 4x+ (y - 8y) + (2z-5z) +6   and 6x-3x-6x + (2y - 10y) + (4 - 8) + (z - 88z)
