Answer:
x = 16
Explanation:
to evaluate for the value of x in the question
3/4(x-4)=9
the first step
use 3 to open the bracket
we have,
3/4 ( x - 4) = 9
3x -12/4 = 9
cross multiply to have a straight equation
3x - 12 = 4 x 9
3x - 12 = 36
3x = 36 + 12
3x = 48
divide both sides by the coefficient of x which is 3
3x/3 = 48/3
x = 16
