Distribute -2 to the eq in ( ). -6b - 4 + 7b - 2 = 0 b = 6
OpenStudy (anonymous):
Can you show me how to check this please
OpenStudy (anonymous):
Put 6 back in for b and simplify to see if your answer is 0
OpenStudy (anonymous):
So -2(3(6)+2)+(7(6)-2)=0 because 3*6 is 18 + 2 is 20. -2*20=-40 7*6 is 42 - 2 is 40 so -40+40=0
