How do you solve \frac { 2} { x } = \frac { 10} { 40}2x=1040?

2 Answers

Do the opposite to solve for x

Explanation:

Start by removing the parenthesis represented by the division signs

x * 40 *( 2/x) = x *40 *( 10/40)x40(2x)=x40(1040)

This results in

80 = 10 x 80=10x

Next divide both sides by 10

80/10 = (10x)/108010=10x10

The answer is

8 = x 8=x
