Question

35=3x+14 could anyone help me fast please I also need to show work!

Answer 1

Answer:

$\boxed {\tt x=7}$

Step-by-step 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.

$\frac{21}{3} =\frac {3x}{3}$

$\frac{21}{3}=x$

$7=x$

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.

Answer 2

Answer:

x = 7

Step-by-step 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 :)
