1). Add ' 3k ' to each side of the equation.
2). Add ' 5 ' to each side.
3). Divide each side by ' 3 ' .
a equals 5
This is already the equation. Now you just have to solve it. x=5.
x+y=5
The equation does not have a solution.
x equals 4 over 35
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
6
Set up the equation and solve: x + 5 = -13 (next subtract 5 from each side of the equation to solve for x) x = -18
3x+5=20 3x=15 x=5
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.
