Question
Solve: $\frac{ z }{7}+1=2 \frac{1}{2}$
✓
Answer
$\frac{ z }{7}+1=2 \frac{1}{2}$
$\Rightarrow \frac{ z }{7}+1=\frac{5}{2}$
$\Rightarrow \frac{ z }{7}=\frac{5}{2}-1$
$\Rightarrow \frac{ z }{7}=\frac{5-2}{2}$
$\Rightarrow \frac{ z }{7}=\frac{3}{2}$
$\Rightarrow z =\frac{3}{2} \times 7$
$\Rightarrow z =\frac{21}{2}$
$\Rightarrow z =10 \frac{1}{2}$
$\Rightarrow \frac{ z }{7}+1=\frac{5}{2}$
$\Rightarrow \frac{ z }{7}=\frac{5}{2}-1$
$\Rightarrow \frac{ z }{7}=\frac{5-2}{2}$
$\Rightarrow \frac{ z }{7}=\frac{3}{2}$
$\Rightarrow z =\frac{3}{2} \times 7$
$\Rightarrow z =\frac{21}{2}$
$\Rightarrow z =10 \frac{1}{2}$
