Reason What is a first step to solving for x in the equation 9x - 7 = 10? How would you
check your solution? © MP.2

let's solve for x :

first step : adding 7 on both sides

next step : dividing by 9 on both sides :

now, let's check for the solution by Plugging the value of x as 17 / 9 in the above equation.

we can see that the LHS = RHS, therefore our value for x is correct. i.e 17 / 9

  the correct choice is marked
