Question

Write the following as an equation:
"2 times a number, x, is equal to 6 less than x"

Answer 1

-6

Explanation:

2x = x-6

subtract x from both sides

x = -6

Answer 2

2x=x-6

Explanation:

2 times a number -> 2x

6 less than x -> x-6

Our equation would be:

2x=x-6

Subtract x from both sides.

2x-x=x-x-6

Combine like terms

x=-6
