-15=5a+12-2a+6
Help me solve this please

Step-by-step explanation:

You have to combine the like terms 5a and 2a which would be 3a

Then 12 and 6 which would be 18

First combine the like terms together first.

1) -15 = 3a + 18

Now you have to get the variable on one side.

2) Do -15 - 18, which is -33. The problem now becomes -33 = 3a.

3) Now you have to solve for a. The next step is -33 divided by 3, which becomes -11 = a.

4) - 11 is now your answer for a.

5) If you want to, you can check.

-15 = 5 (-11) + 12 - 2(-11) + 6

-15 = -55 + 12 + 22 + 6

-15 = -15

- 15 =

B. y=2.25x+4.00 (eg. 2020)
