Solve the equation ( 1 point) 3/4x=9
a) x=12
b) x=108
c) x=72
d) x= 4/9

x = 12

Step-by-step explanation:

Solve for x:

(3 x)/4 = 9

Multiply both sides of (3 x)/4 = 9 by 4/3:

(4×3 x)/(3×4) = 4/3×9

4/3×3/4 = (4×3)/(3×4):

(4×3)/(3×4) x = 4/3×9

4/3×9 = (4×9)/3:

(4×3 x)/(3×4) = (4×9)/3

(4×3 x)/(3×4) = (3×4)/(3×4)×x = x:

x = (4×9)/3

9/3 = (3×3)/3 = 3:

x = 4×3

4×3 = 12:

 x = 12
