Which of the following values of r will result in a true statement when substituted into the given equation? -r + 5(r + 2) = -10

A. r = -6
B. r = -5
C. r = 0
D. r = 1

the right answer is -5 (B)

Step-by-step explanation:

-(-5) +5(-5+2)

5 + -15 = -10

B. r = -5 is the answer.

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10
