Answer:
x = 10
Step-by-step explanation:
[tex]x - 7 = 13 - x[/tex]
Step 1 : Collect like terms and simplify
[tex]x + x = 13 + 7 \\ 2x = 20[/tex]
Step 2 : Divide both sides of the equation by 2
[tex] \frac{2x}{2} = \frac{20}{2} [/tex]
Step 3 : Simplify by cross cancellation of common term : 2
[tex]x = 10[/tex]
