Solving Linear Equations.
Solve for x.
(2/7)/x = (3/7)/(9/10)
(2/7)/x = 10/21 Simplify the equation
(2/7)(21) = (10)(x) Cross Multiply
6 = 10x
6/10 = (10x)/(10) Divide both sides by 10
3/5 = x
So therefore, x = 3/5
Check:
Evaluate to check.
(2/7)/x = (3/7)/(9/10)
(2/7)/(3/5) = (3/7)/(9/10)
10/21 = 10/21
x = 3/5
