Question

Solve for x. 3x/2 = 15 x = 22 1/2 x = 10 1/2 x = 10 x = 1/10

Answer 1

10

Explanation:

Solve for x:

(3 x)/2 = 15

Multiply both sides of (3 x)/2 = 15 by 2/3:

(2×3 x)/(3×2) = 2/3×15

2/3×15 = (2×15)/3:

(2×3 x)/(3×2) = (2×15)/3

(2×3 x)/(3×2) = (3×2)/(3×2)×x = x:

x = (2×15)/3

15/3 = (3×5)/3 = 5:

x = 2×5

2×5 = 10:

Answer: x = 10

Answer 2

x = 10

Explanation:

(3x)/2 = 15 is your question.

Isolate the variable (x). Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS (Parenthesis, Exponent (& roots), Multiplication, Division, Addition, Subtraction).

First, multiply 2 to both sides

((3x)/2) = (15)(2)

3x = (15)(2)

3x = 30

Next, to isolate the variable (x), divide 3 from both sides

(3x)/3 = (30)/3

x = 30/3

x = 10

x = 10 is your answer
