6. Combine like terms. What is the simplified form of the expression?
6a + 8 + 2a – 6
=

6a + 8 + 2a – 6

we calculate the unknowns of the same type alone (x with x, a with a, y with y ...) and the digits / numbers alone .

6a+2a=8a

8-6=+2

So 8a+2

x= -3

step-by-step explanation:

step 1: simplify brackets

4 - x - 1 = 6

step 2: simpilfy

3 - x = 6

step 3: subtract 3 from both sides

-x = 6 - 3

step 4: simpilfy 6 - 3

-x = 3

step 5: multiply both sides by -1

x = -3

good luck!
