First, we know (D is dad, J is Jill) that D+J=50.
Second, in 5 years D will be 3 times as old so
(D+5)= 3*(J+5)
Moving on, if we know D+J=50 then D=(50-J) is true.<span>Taking that relationship and substituting for D in the other equation, it becomes
50 - J + 5 = 3 * (J + 5)
Then, it becomes </span>50 - J + 5 = (3 * J) + (3 * 5)
Then, 55 - J = (3 * J) + 15
Then, 55 - 15 = (3 * J) + J
<span>which becomes 40 = 4*J</span>
Answer:
(5,7)
Step-by-step explanation:
x + 2 = 2x - 3
2x - x = 5
x = 5
When X = 5, Y= 7
Best regards
That would be : y = 2x + 1
B I’m sure if not comment correct answer
The answer's D. 35/22
Well i have to write 20 words so dont mind this part
