Question

Solve for b

-8 = b - 2

Answer 1

b = -6

Step-by-step explanation:

Step 1: To solve this equation, add two to both sides. This will isolate the variable (b) and allow us to find its value.

`-8 = b - 2\\(-8 + 2) = b (-2 + 2)\\(-8 + 2) = b\\-6 = b`

Step 2: Switch sides

`-6 = b\\b = -6`

Bonus Step: If you would like to double check that the variable (b) does in fact equal negative six, substitute the value of the variable in the equation and solve.

`-8 = b - 2\\-8 = -6 - 2\\-8 = -8 [ true ]`

Therefore, the value of b in the given equation is -6.

Answer 2

B= -6

Step-by-step explanation:

It's kind of hard to explain but it's like regular math. if the lower number comes first in subtraction, the numbers go into negative. So on a numberline, if we started at -8, and subtracted 2, since 2 is a positive number we would go towards the positive side of the numberline, making it -6. Hopefully this helps lol
