a equals 5
This is already the equation. Now you just have to solve it. x=5.
x+y=5
Add 5 to both sides of the equation to get rid of the - 5. -3x - 5 + 5 = -20 + 5 Solve and simplify. -3x = -15 Divide both sides of the equation by -3. x = 5
Set up the equation and solve: x + 5 = -13 (next subtract 5 from each side of the equation to solve for x) x = -18
x equals 4 over 35
5
The equation does not have a solution.

y=4 x+y=5 so it wud be:::::: x+4=5 solve it from there by doing 1 step equation :)
Subtract two from both sides and you are left with X equals -5
You forgot to include the equation. Just replace y with 5, every time it occurs, then solve the remaining equation for x.
