How do you solve #5x+7=10# by clearing the fractions?

Answer 1

Eva Abramson

#x = 3/5#

#5x + 7 = 10#

Subtract both sides by #color(red)7#

#5x + 7 - color(red)7 = 10 - color(red)7#

#5x + 0 = 10 - 7#

#5x = 3#

Divide both sides by #color(red)5#

#(5x)/color(red)5 = 3/color(red)5#

#cancel((5) x)/cancel5 = 3/5#

#x = 3/5#

To solve the equation 5x + 7 = 10 by clearing the fractions, follow these steps:

Subtract 7 from both sides to isolate the term with the variable: 5x = 10 - 7
Simplify the right side of the equation: 5x = 3
Divide both sides by 5 to solve for x: x = 3/5
