Answer:
13
Step-by-step explanation:
Create an equation: g+(G+4)(2)=35
Parentheses: g+2(G+4)=35
Distributive property: g+2g+8=35
Combine like terms: 3g+8=35
Subtractive property: 3g=27
Division property: g=9
Greg is 9. Since Ava is 4 years older you add 4 to find her age. Ava is 13. You take Ava’s age times 2 ( equals 26) then add Greg’s age (equals 35). And it should equal 35.
