A student tries to solve the equation 2(x-7)+x-9. The student work is shown to the right describe the errors. Then solve the equation correctly

3x - 23

Step-by-step explanation:

To solve the equation goes thus:

= 2(x-7)+x-9.

We have to open the bracket first

= 2x - 14 + x - 9

We then collect like terms

= 2x + x - 14 - 9

= 3x - 23

Therefore, the answer is 3x - 23

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
