Question

Given the equation −2x − 13 = 8x + 7, which order of operations completely solves for x? (1 point) 1Points A Add 2x, then subtract 8x, lastly subtract 7 B Add 2x, then add 13, lastly divide by 10 C Subtract 8x, then add 13, lastly divide by −10 D Subtract 8x, then add 2, lastly add 13

Answer 1

Answer:

Subtract 8x, then add 13, lastly divide by −10                     option C

Explanation :

We have a linear equation-

−2x − 13 = 8x + 7

Step 1:  Combine like terms, we move 8x from right side to leftt side.

             So, Subtract 8x both the side

                -10x -13 =  7

Step 2:   Now move 13 from left side to right side.

                add 13 both the side

           - 10x = 20

Step 3:  Divide -10 both the side.

             $\frac{-10x}{-10} = \frac{20}{-10}$

             x = -2
