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

step-by-step explanation:

through just a quick inspection, one can see that the graph of this cubing function starts in quadrant iii and ends in quadrant i.   when x = 0, y = 3, so the y-intercept is (0, 3).

if graphs are part of the problem statement, share them.   .
