Is x= 6 a solution to the equation –18 = -2(x + 3)?

yes, x=6 is a solution

Step-by-step explanation:

-18 = -2(6+3)

-18 = -2(9)

-18= -18

Yes, it is

Step-by-step explanation:

If you substitute the value of x into the equation, we would get:

-18=-2(6+3)

By using BIDMAS (or whatever else people use, BODMAS, PEDMAS), we first have to do the brackets. In the brackets we have 6+3 (which equals 9).

Now our equation can be simplified to -18=-2(9).

Now  we simply multiply -2 with 9, as a number next to something in a bracket usually means multiplication. If you multiply a positive by a negative, the product will be negative. Therefore, -9 x 2 = -18.

This proves it is a correct solution.
