Question

Find the mistake made in the steps to solve the equation below. 6x - 1 = -2x + 9

Answer 1

Since you do not have a picture, i will give you the steps, and you can see where the differences are at.

6x - 1 = -2x + 9

Note the equal sign. What you do to one side, you do to the other. Isolate the x.

First, add 1 to both sides

6x - 1 (+1) = -2x + 9 (+1)

6x = -2x + 10

Next, add 2x to both sides to isolate the x

6x (+2x) = -2x (+2x) + 10

6x + 2x = 10

8x = 10

Finally, isolate the x by dividing 8 from both sides

8x/8 = 10/8

x = 10/8 (may be where they stopped at, but you can go further)

Simplify. Divide 2 from top and bottom

(10/8)/(2/2) = 5/4

x = 5/4 should be final answer


hope this helps
