You have the system of two equations with two unknowns:

.

Multiply the first equation by 2 and the second equation by 3. You will get

.

Now distract the first equation from the second one. You will get

5x = 60 - 10,

5x = 50,

x = 10.

Next, substitute the found value of x into the first equation . . . . . .

Please complete it yourself.
