What value of b makes the statement true? 17 = b – (–6.2) A. –23.2 B. –10.8 C. 10.8 D. 23.2

OpenStudy (jacobciezki):

you have to put each number in the b spot so try that and you will get your answer

OpenStudy (jacobciezki):

what you get when you put a in b slot

OpenStudy (triciaal):

or to do it algebraically isolate the variable to one side and whatever you do to one side of an equation also do to the other to maintain the balance

OpenStudy (triciaal):

then simplify by adding like terms

OpenStudy (anonymous):

no not c ITS D

OpenStudy (triciaal):

just for reference and later, whenever the variable has a coefficient greater than one divide by the coefficient to get the variable

OpenStudy (anonymous):

Try 17 - -6.2=? Then reverse it. I say its D.
