Answer:
S = x + 10
R = 2x + 10
Step-by-step explanation:
If R is Roberto's age, and S is his sister's age, then:
R = S + x
R − 10 = 2 (S − 10)
Solve with substitution.
S + x − 10 = 2 (S − 10)
S + x − 10 = 2S − 20
80
Plug it in.
So 5 x 2 (4 x 3- 2 x 2)
5x2(12-2x2)
5x2(12-4)
5x2(8)
(10)(8)
So, the answer is 80.
