answer
5 numeric 1 point
solve. -3x + 7 = -8
answer
6 numeric 1 point
solve. 2x - (-5) = -3
answer
7 numeric 1 point
solve. 2(x + 3) = -16
answer

Explanation:

Step1: Solve for x in -2x + (-5) = 7

First, simplify the left side: $-2x - 5 = 7$
Add 5 to both sides: $-2x = 7 + 5$
$ -2x = 12$
Divide by -2: $x = \frac{12}{-2} = -6$

Step2: Solve for x in -3x + 7 = -8

Subtract 7 from both sides: $-3x = -8 - 7$
$-3x = -15$
Divide by -3: $x = \frac{-15}{-3} = 5$

Step3: Solve for x in 2x - (-5) = -3

Simplify the left side: $2x + 5 = -3$
Subtract 5 from both sides: $2x = -3 - 5$
$2x = -8$
Divide by 2: $x = \frac{-8}{2} = -4$

Step4: Solve for x in 2(x + 3) = -16

Divide both sides by 2: $x + 3 = \frac{-16}{2}$
$x + 3 = -8$
Subtract 3 from both sides: $x = -8 - 3 = -11$

Answer:

1. $x = -6$
2. $x = 5$
3. $x = -4$
4. $x = -11$
