Do the opposite to solve for x

Start by removing the parenthesis represented by the division signs

# x * 40 *( 2/x) = x *40 *( 10/40)#

This results in

# 80 = 10 x #

Next divide both sides by 10

# 80/10 = (10x)/10#

The answer is

# 8 = x #

#x=8#

We can use cross-multiplication to get

#10x=80#

Lastly, we can divide both sides by #10# to get

#x=8#

Hope this helps!
