How do you simplify this problem?
I really need help.I need it step by step so I could understand it.Please help.Thanks.
b-[x+4a+(x-7)]
To simplify the given problem (b - [x + 4a + (x - 7)]), follow these steps:
Step 1: Distribute the negative sign inside the parentheses. This means you need to distribute the negative sign to every term inside the parentheses.
b - [x + 4a + x - 7]
Step 2: Combine like terms by adding or subtracting. In this case, combine the x terms and the constants.
b - [2x + 4a - 7]
Step 3: Distribute the negative sign outside the brackets to every term inside the brackets.
b - 2x - 4a + 7
Step 4: Rearrange the terms if desired.
-2x + b - 4a + 7
So, the simplified form of the expression b - [x + 4a + (x - 7)] is -2x + b - 4a + 7.
