You should just multiply the first equation by 3 so you will have :
3 ( 3x+y= 7 ) ⇒ 9x + 3y = 21 so now you have the missing values and they are 3 and 21 :))

Answer: x=5.33333333333
Step-by-step explanation:
6=x+2/3
We simplify the equation to the form, which is simple to understand
6=x+2/3
Simplifying:
6=x + 0.666666666667
We move all terms containing x to the left and all other terms to the right.
-1x=0.666666666667-6
We simplify left and right side of the equation.
-1x=-5.33333333333
We divide both sides of the equation by -01 to get x.
x=5.33333333333
