Answer 1

What is the solution of 3/4x = 12

Answer 2

The equation is this
\[\Large \frac{3}{4}x = 12\]
right?

Answer 3

yes

Answer 4

The first step is to multiply both sides by 4
\[\Large \frac{3}{4}x = 12\]
\[\Large 4*\frac{3}{4}x = 4*12\]
\[\Large 3x = 48\]
notice how the 4's on the left side cancel out which eliminates the fraction

Answer 5

Unfortunately, 3/4x = 12 is ambiguous. One wonders whether you mean (3/4)x = 12 or 3/(4x) = 12. Please use parentheses to impart added clarity.

Answer 6

Muliplying both sides by 4 clears your equation of fractions, which is helpful.

Answer 7

So D right?

Answer 8

yep, divide both sides by 3 to get x = 16

Answer 9
