Question

Steven is three times as old as Jenny. The sum of their ages is 63. Let S be Steven’s age and J be Jenny’s age. Select the system of equations that represent the problem?

( A) S=3J

S+J=63


(B) S=J+3

S+J=63


(C) S=3J

SJ=63

Answer 1

The answer would be A because S = 3J shows that steven (S) is (=) 3 times older than Jenny 3J

And S + J = 63 shows that the sum of their ages (S + J) is equal to 63 (= 63)
