Answer:
[tex]\boxed {\tt x=7}[/tex]
Step-by-step explanation:
We are given the equation
[tex]35=3x+14[/tex]
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.
[tex]35-14=3x+14-14[/tex]
[tex]35-14=3x[/tex]
[tex]21=3x[/tex]
x is being multiplied by 3. The inverse of multiplication is division. Divide both sides of the equation by 3.
[tex]\frac{21}{3} =\frac {3x}{3}[/tex]
[tex]\frac{21}{3}=x[/tex]
[tex]7=x[/tex]
Let's check our solution. Plug 7 in for x and solve.
[tex]35=3x+14[/tex]
[tex]35=3(7)+14[/tex]
[tex]35=21+14[/tex]
[tex]35=35[/tex]
This checks out, so we know our solution, x=7 is correct.
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 :)
