Answer:
Ava is 26 and Grace age is 9
Step-by-step explanation:
x=ava's age
y=grace's age
3y-1=x
x+y=35
Substitute 3y-1 to x+y=35 for the value of x to find grace age
3y-1+y=35
4y-1=35
+1 +1
4y=36
y=9 now substitute 9, the y value in 3y-1=x to find ava's age
3(9)-1=x
x=26
to verify; 26+9=35
true 35=35
