Question

3(2c + 5) = 39 What is the answer ?

Answer 1

Answer:

 =  4

Step-by-step explanation:

Subtract  15 from both sides of the equation

6+15=39

6+15−15=39 − 5

Simplify

6=24

Divide both sides of the equation by the same term

(6=24)/6

Simplify

=4

Answer 2

Answer:

c=1

Step-by-step explanation:

Simplifying

3 + 2c = 5

Solving

3 + 2c = 5

Solving for variable 'c'.

Move all terms containing c to the left, all other terms to the right.

Add '-3' to each side of the equation.

3 + -3 + 2c = 5 + -3

Combine like terms: 3 + -3 = 0

0 + 2c = 5 + -3

2c = 5 + -3

Combine like terms: 5 + -3 = 2

2c = 2

Divide each side by '2'.

c = 1

Simplifying

c = 1
