Given:
7x + 8 = 5x + 12
Let's solve for x
First step:
Subtract 8 from both sides
7x + 8 - 8 = 5x + 12 - 8
7x = 5x + 4
Next step:
Subtract 5x from both sides
7x - 5x = 5x - 5x + 4
2x = 4
DIvide both sides by 2:
[tex]\begin{gathered} \frac{2x}{2}=\frac{4}{2} \\ \\ x\text{ = 2} \end{gathered}[/tex]ANSWER:
x = 2
