Question

Tell whether the statement is True or False.
316x - 2) - 7 = 18x - 13

Answer 1

True

Explanation:

You want to get the x's by themselves, so first you have to use the distributive property.

3 x 6x = 18x

3 x 2 = 6

So now the equation should look like

18x - 6 - 7 = 18x - 13

So now you have to get the x's by itself by adding or subtracting like terms.

- 6 - 7 = -13

18x - (-13) = 18x - 13

+ (-13) + (-13)

-----------------------

18x = 18x

18/18 18/18

x = 1

Now plug the numbers in

3(6(1) - 2) - 7 = 18(1) - 13

5 = 5

Answer 2

True.

Explanation:

Multiply 3 by 6x-2 and you get (18x-6). Subtract 7 from -6 gives you 13, which equals 18x-13.
