3x+3 = 24
Subtract 3 from both sides:
3x = 21
Divide both sides by 3 to find the value of x:
x = 7
You would take 2 and replace it for x in your other equation and solve.
This equation is unsolvable since there are two unknowns and only one equation. You would require a second equation in order to solve it.
You'd need another equation to sub in
Add 8
Can't be done unless you have another equation with the same x and y. Then you would solve for simultaneous equations.
You would take 2 and replace it for x in your other equation and solve.
You would do it it by oppisites. 3+2+4=9 which equals C.
-4
This equation is unsolvable since there are two unknowns and only one equation. You would require a second equation in order to solve it.

Because this equation has four variables, it would require four unique equations involving only these four variables to solve.
Can't be done unless you have another equation with the same x and y. Then you would solve for simultaneous equations.
The equation you are looking for is x + 5 = 0. To solve for x, you would subtract 5 from both sides of the equation. This would give you x = -5. Therefore, -5 plus 5 equals 0.
if the equation was 7x = 42. The answer would be x = 6
