Answer:

x = 7

Explanation:

First using the culamtive property lets change how this problem is set up.

35 = 3x + 14

14 + 3x = 35

Now that we have done that we need to subtract or add the common number to both sides.

14 + 3x = 35

- 14 - 14

3x = 21

Now to find our final solution divide both sides by the number next to the variable so in our case 3.

3x / 3 = x

21 / 3 = 7

Now we have our final solution.

x = 7

Hope this helps :)

Answer:


\boxed {\tt x=7}

Explanation:

We are given the equation


35=3x+14

We want to solve for x, therefore we must isolate x on one side of the equation.

14 is being added to 3x. The inverse of addition is subtraction. Subtract 14 from both sides of the equation.


35-14=3x+14-14


35-14=3x


21=3x

x is being multiplied by 3. The inverse of multiplication is division. Divide both sides of the equation by 3.


(21)/(3) =\frac {3x}{3}


(21)/(3)=x


7=x

Let's check our solution. Plug 7 in for x and solve.


35=3x+14


35=3(7)+14


35=21+14


35=35

This checks out, so we know our solution, x=7 is correct.
