Answer:

x=11

Step-by-step explanation:

1. Write the equation.

3x+5=7x-39

2. Isolate the 3x from the 5.

3x+5=7x-39

    -5       -5

3x=7x-39-5

3. Move the 7x to the other side.

3x=7x-39-5

-7x  -7x

-4x=-39-5

4. Simplify.

-4x=-44

5. Isolate x by dividing by -4 on each side.

[tex]\frac{-4x}{-4}[/tex]=[tex]\frac{-44}{-4}[/tex]

6. Since the negatives cancel each other out and 44 divided by 4 is 11, the answer is positive 11.
