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

d (5 x (-20)) * (100 x (0.7))

step-by-step explanation:

5÷1/100 * -.7 *-20

copy dot flip

5*100 * -.7 *-20

rearrange

5*-20   * 100 *-.7

-100   *-70
