Kadesha is simplifying the expression below.
-(x-3) - 2(x-1)
she lists the steps that she uses to simplify the expression as follows:
step 1: distribute –1 through (1-3), and distribute-2 through (x-1).
step 2: rewrite the expression as -x-3-2x-2.
step 3: combine - and -2x, and combine -3 and -2.
step 4: the simplified expression is -3x-5.
in which step did kadesha make the first error?
she made the first error in step 1 because only -2 should be distributed through the parentheses.
she made the first error in step 2 because step 2 should be -x+3-2x+2.
she made the first error in step 3 because -x and -2x cannot be combined.
she made the first error in step 4 because the simplified expression is -x-5.
