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 do it it by oppisites. 3+2+4=9 which equals C.

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.
if the equation was 7x = 42. The answer would be x = 6
None. Properties of inequalities are not that relevant when solving equalities.
75 percent is equal to 0.75, so the expression would look like (0.75x) +8. But if you do not know what it equals to it is not an equation and you can not solve it.
