How do you solve #(3+x)/8=7/12#?

Answer 1

Ethan Adkins

#x = 20/12 = 5/3#

Cross multiplying is the simplest way to solve an equation where there is one fraction on each side of the equal sign.

#12(3+x) =7xx8#

#36 +12x = 56#

#12x= 20#

#x = 20/12 = 5/3#

To solve the equation (3 + x) / 8 = 7 / 12:

Multiply both sides of the equation by 8 to eliminate the fraction: 8 * (3 + x) / 8 = (7 / 12) * 8.
Simplify both sides: 3 + x = 7/12 * 8.
Solve for x: x = (7/12) * 8 - 3.
