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.
