Question

How do I find what x is in this equation. 1 2/5x =7 What is x?

Answer 1

Solution

1) Convert 1 $\frac{2}{5}$ to improper fraction. Use this rule: abc=ac+bc
$\frac{5+2}{5}$ x =7

2)Simplify 5+2 to 7
$\frac{7}{5}$ x =7

3)Simplify $\frac{7}{5}$ x to $\frac{7x}{5}$
$\frac{7x}{5}$ = 7

4) Multiply both sides by 5
7x=7×5

5)  Simplify 7×5 to 35
7x=35

6) Divide both sides by 7
x= $\frac{35}{7}$

7) Simplify $\frac{35}{7}$ to 5
x=5

Answer 2

If you would like to solve the equation 1 2/5 * x = 7, you can calculate this using the following steps:

1 2/5 * x = 7
7/5 * x = 7      /*5/7
x = 7 * 5/7
x = 5

The correct result would be 5.
