Answer:
The value of x is 200.
Step-by-step explanation:
Given equations,
[tex]\frac{1}{5}x-\frac{2}{3}y=30----(1)[/tex]
[tex]y=15-----(2)[/tex]
By substituting the value of y from equation (2) in equation (1),
[tex]\frac{1}{5}x-\frac{2}{3}\times 15=30[/tex]
[tex]\frac{x}{5}-2\times 5=30[/tex]
[tex]\frac{x}{5}-10=30[/tex]
[tex]\frac{x}{5}=40[/tex]
[tex]x=5\times 40=200[/tex]
Hence, the value of x is 200.
