To solve for x in the given equation;
[tex]5x+7=3x-9[/tex]We start by collecting like terms, as follows;
[tex]5x-3x=-9-7[/tex]When a number crosses the sign of equality, the sign in front of it switches. Positive numbers becomes negative, and vice versa.
We would now have;
[tex]\begin{gathered} 5x-3x=-9-7 \\ 2x=-16 \\ \text{Divide both sides by 2;} \\ \frac{2x}{2}=\frac{-16}{2} \\ x=-8 \end{gathered}[/tex]ANSWER:
The answer is x = -8
