Question

The sum of three integers is 92. The second number is three times the first number. The third number is ten less than twice the first number. Find the integers.

Answer 1

a, b, and c are our 3 integers.

Can you make equations using a, b, and c using what you were given in your question?

Answer 2

A + B + C = 92

Answer 3

B= A(3)

Answer 4

C= (A-10) * 2

Answer 5

Now substitue the 2 last equations into the first one :)

Answer 6

A + (A(3)) + ((A - 10)(2)) = 92

Answer 7

i think the equation for c is close, but not correct

Answer 8

c = 2a - 10 i think

Answer 9

I am not sure

Answer 10

but yeah after you fix that and plug it in, you just solve for A

Answer 11

Yes, c = 2a -10 is correct.

Solve for a, then you can solve for b and c by using the last 2 equations.
