Remove the brackets and simplify the following expression.
First, let's remove the brackets in -(5x -3).
Multiply -1 and -3 together. You will get -5x. Note that "-" is the same as "-1"
Now, multiply -1 and -3 together. You will get +3.
Put back -5x +3 into the expression. Next, we remove the brackets in 2(4x -2).
Now, multiply 2 and 4x together. You will get +8x.
Now, multiply 2 and -2 together. You will get -4.
Put back 8x -4 into the expression. The expression now becomes:
Notice that this expression has like terms. Therefore, let's arrange the like terms together. The expression now becomes:
Now, simplify the expression by adding +3 and -4. You will get -1.
Now, simplify the expression by adding +8x and -5x. You will get 3x.
The expression becomes 3x-1. There is no more like terms, therefore this is the simplest expression. Clearly, the answer is C.
