Question

z+7/2=8 solve and check​

Answer 1

Answer:

z=8-7/2

z= 8-3.5

z=4.5

Step-by-step explanation:

check= 4.5+7/2=8

4.5+3.5=8

Answer 2

${ \huge{ \color{pink}{ \underline{ \underline{ \sf{ \color{aqua}{คຖŞຟēr}}}}}}}$

$\sf{z + \frac{7}{2} = 8 }$

$\sf{ = > z = 8 - \frac{7}{2} }$

$\sf = > z = \frac{8}{1} - \frac{7}{2}$

Take L.C.M. to make the denominators same.

L.C.M. of 1 and 2=2

______________________

$\sf = > \frac{8}{1} \times \frac{2}{2} = \frac{16}{2}$

$\sf= > \frac{7}{2} \times \frac{1}{1} = \frac{7}{2}$

$\sf = > z = \frac{16 + 7}{2} = \frac{13}{2}$

${\large { \color{aqua} {\boxed{ \color{pink}{\sf {❥Hope \: it \: helps \: you....}}}}}}$
