Question

Which equation, when solved, gives 8 for the value of x?
a. 5/2x + 7/2=3/4x + 14
b. 5/4x - 9=3/2x -12
c. 5/4x - 2=3/2x - 4
d. 5/2x - 7=3/4x +14

Answer 1

option c will be the answer. for solution, refer to the attached photo!!

also there is a faster method if it is an objective question.

we can just put '8' in the place of x and check if LHS=RHS.

If we get LHS=RHS, it means x=8 will satisfy that particular equation.
