How do you solve #4( 9+ x ) = 136#?
2 Answers
Explanation:
#"distribute the bracket on the left side of the equation"#
#rArr36+4x=136#
#"subtract 36 from both sides"#
#cancel(36)cancel(-36)+4x=136-36#
#rArr4x=100#
#"divide both sides by " 4#
#(cancel(4) x)/cancel(4)=100/4#
#rArrx=25#
#color(blue)"As a check"# Substitute this value into the left side and if equal to the right side then it is the solution.
#"left "=4xx34=136=" right side"#
#rArrx=25" is the solution"#
Explanation:
First you have to expand the equation:
Then subtract both sides of equation by 36 to isolate the unknown's (
Dividing both sides by 4, we get the value of
