    All you have to do is pick your favorite variable from one equation (v or a) and solve for it, then substitute whatever answer you get into the other equation.

    I think the 'v' variable would be easiest to work on here

    if u want to solve for a u plug in v-3 into the top equation for a. if u want to solve for v u plug in 3+a into the top equation for v

    5a-v=-23 -a+v=3 (copied so that I may see it properly) 5a-v=-23 Subtract 5a from both sides now -v = -23 -5a But the variable cannot be negative. Multiply both sides by -1. v = 23 + 5a Now substitute this equation into - a + v = 3, in the 'v' slot.
