Question

What is the value of x in the equation 5(2x−4)/3+9=14

Answer 1

x = 3.5

Explanation:

This assumes the equation is correct as written, and not 5(2x−4)/(3+9)=14

5(2x−4)/3+9=14

(10x−20)/3 + 9 = 14 [expand brackets]

(10x−20)/3 = 5 [subtract 9 from both sides]

10x−20 = 15 [multiply both sides by 3]

10x = 35 [add 20 to both sides]

x = 3.5 [divide both sides by 10]

Answer 2

x=18.8

Explanation:

2 multiply by 18.8=37.6

multiply this by 5 you get 188

minus by 5 multiply by 4 which is 20

188-20=168

168/3+9=168/12=14

therefore x is equal to 18.8
