Answer:
Do -7 + 7 and do the same to 10, (7 + 10). This is the first step in Isolating the variable. Remember, what you do to one side you have to do to the other.
The solution of given equation is, [tex]x=\frac{17}{9}[/tex]
Given equation is, [tex]9x-7=10[/tex]
To solve for x, our first step is add 7 on both side of equation.
[tex]9x-7+7=10+7\\\\9x=17\\\\x=\frac{17}{9}[/tex]
To check the solution is correct or not.
Substitute value of x in given equation.
[tex]9*\frac{17}{9} -7=10\\\\17-7=10\\\\10=10[/tex]
Since, both left and right parts are equal. Therefore, our solution is correct.
