Question

3 - z/4 = 8 what is the solution of this equation ?

Answer 1

$\bold{Hey\ there!}$

1. $\bold{3-\frac{z}{4}=8; \rightarrow 3+\frac{-1}{4}=8}$$\bold{\frac{-1}{4}z+3=8}\\\\ \bold{Subtract\ by\ the\ number\ 3\ on\ your\ sides\downarrow}\\\\\bold{Like:\frac{-1}{4}z+3=8-3}\\\bold{Cancel:3-3\ because\ that\ gives\ us\ the\ result\ of\ 0}\\\bold{Keep:8-3\ because\ it\ helps\ us\ solve\ for\ our\ \underline{ANSWER}}\\\\\bold{Multiply\ by\ -4\ on\ each\ of\ your\ sides}\\\bold{Like:-4(\frac{-1}{4}z)}=-4(5)\\\bold{Cancel:-4(\frac{-1}{4}) \ because\ it\ gives\ you\ the\ result\ of\ 1}\\\bold{Keep:-4(5)because\ it\ gives\ you\ your\ \underline{ANSWER}}$$\boxed{\boxed{\bold{Answer:z=-20}}}\checkmark \\ \\ \bold{Good\ luck\ on\ your\ assignment\ \& \ enjoy\ your\ day!} \\ \\ \\ \\ \frak{LoveYourselfFirst:)}$
