Question

If 7a + 6g = 31.40 and 5a + 10g = 37.00 what do variables a and g equal?

Answer 1

There are a number of ways to solve this, what we could do is get a from equation 1 and subsitute it in equation 2 so we'll find g then we can put that value to find a

Answer 2

Ok that sounds good can you show me how?

Answer 3

from 5a+10g=37, rearrange to 5a=37/10g
divide both sides by 5, a=37/50g
just plug that a into the other equation and solve for g then once you have g plug that in to either one and solve for a
