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

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.

`(-10x)/(-10)  = (20)/(-10)`

x = -2
