Question

Please help, I don't understand this.

Answer 1

Answer: -21

Step-by-step explanation:

To begin, we can combine like terms, -0.66 and 0.36 are coefficients with the same variable.

This gives us -0.66x+0.36x= -0.30x, and the equation becomes -0.30x=6.3.

Next, we can simply solve for x by dividing 6.3 by -0.30, and that gives us x=-21.

Answer 2

-0.3

Explanation:

just sum -0.66x and 0.36x
