The second of two numbers is 5 more than twice the first

Answer 1

S=5+2F

2F = S-5

F = (S-5)/2

You can write the First (F) in terms of the second number (S), or S in terms of F, but you can't solve for either

without more information.

If you graph S on the y axis and F on the x axis, you get a straight line with slope = 2 and y intercept of 5
