(2/7)/x=(3/7)/(9/10)

Sagot :

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
