Answer:
Explanation:
First, let us subtract 7 from both sides of the equation; this gives
[tex]7-3x-7=4-7[/tex][tex]\Rightarrow-3x=4-7[/tex][tex]\Rightarrow-3x=-3[/tex]Finally, dividing both sides by -3 gives
[tex]-\frac{3x}{-3}=-\frac{3}{-3}[/tex][tex]\Rightarrow x=-\frac{3}{-3}[/tex][tex]\boxed{x=1.}[/tex]Which is our answer!
Hence, the solution to the equation is x = 1.
