Answer:
x = 5
Step-by-step explanation:
The given expression is
[tex]1\frac{2}{5}x=7[/tex]
So, to solve this equation, we first have to transform the mixed number into a fraction
[tex]1\frac{2}{5}x=7\\\frac{7}{5}x=7[/tex]
Now, we isolate x and solve
[tex]\frac{7}{5}x=7\\x=\frac{7(5)}{7}=5[/tex]
Therefore, the solution is 5.
