Question

Solve for variable x:
5=12/x (5 equals 12 over x)
A. 5/12
B. 4.12
C. 12/5
D. 2.75

Answer 1

multiply both sides by x then divide both sides by 5.

Answer 2

\[5=\frac{ 12 }{ x }\]
\[5*x=\frac{ 12 }{ x }*x\] here x divides out on the right side of the equation.
\[\frac{ 5x }{ 5 }=\frac{ 12 }{ 5 }\] here it's the same with five on the left side
\[x=\frac{ 12 }{ 5 }\]finally you're left with x

Answer 3

the LCD of 1 and x = x so multiply each side by x
to get 1 x divide by the coefficient
if you have 5x divide by 5 to get x if you had 10 a = 20 you would divide by 10 to get a = 2

Answer 4

thank you both. appreciate it
