Question

Solve this equation: 4(3x+2)=68

Answer 1

x = 5

Explanation:

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Also, follow PEMDAS.

First, distribute 4 to all terms within the parenthesis:

4(3x + 2) = (4)(3x) + (4)(2) = 12x + 8

12x + 8 = 68

Isolate the variable x. Subtract 8 from both sides.

12x + 8 (-8) = 68 (-8)

12x = 68 - 8

12x = 60

Isolate the variable, x. Divide 12 from both sides.

(12x)/12 = (60)/12

x = 60/12

x = 5

5 is your answer for x.

Answer 2

x=5

Explanation:

4(3x+2)=68

Divide each side by 4

4/4(3x+2)=68/4

3x+2 =17

Subtract 2 from each side

3x+2-2 = 17-2

3x = 15

Divide each side by 3

3x/3 = 15/3

x =5
