Answer:

C

Step-by-step explanation:

First you distribute and multiply both 4x and -5 by 6. This gives you the following equation:

24x-30=42

Next, you add 30 to both sides, giving you:

24x=72

Finally, you divide it all by 24, leaving you with

x=3

I need help its math
Degger [83]

Given: w²+9=6w [0, 3, 6, 9]

We need to substitute each number for w and find which works

Sub Zero: 0²+9=6×0

Simplify: 9=0. 9 does not equal 0, so it is not 0

Sub Three: 3²+9=6×3

Simplify: 9+9=18

Addition: 18=18

The statement 18=18 is true, therefore we have our answer.

Answer: The second option is correct. 3 would be the correct number to substitute to make the equation correct.
