    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

    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
