Sagot :
Answer:
sandrea is correct
Step-by-step explanation:
Fernando is incorrect because when he brought over the 4a to the other side, he removed the negative sign from the 5b.
also, there shouldn't really be a negative number in the denominator, so the answer should really be :
(-7 + 4b)/5
but sandrea is still correct
Answer and Step-by-step explanation:
Sandrea solved for b correctly.
Both are given the equation 4a - 5b = 7
To solve, we have to get b by itself, so first we subtract 4a from both sides of the equation.
(4a - 5b) - 4a = (7) - 4a
-5b = 7 - 4a
Now we divide both sides of the equation by -5.
[tex]\frac{-5b}{-5}=\frac{7-4a}{-5} \\\\b = -\frac{7-4a}{5}[/tex]<- That is your final answer.
Fernando got rid of the negative when subtracting 4a from both sides of the equation.
