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.

anonymous · Answer

solve for what

anonymous · Answer

idk please just help me solve it

theslytherinhelper · Answer

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

anonymous · Answer

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

theslytherinhelper · Answer

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.
