Question

a)58xX-934=6722

b)2005+Xx34=5337

c)12xXx15=38880

Answer 1

58xX=7656

      X=132

b Xx34=5337-2005

Xx34=3332

X=98 

12xX=38880/15

12xX=2592

X=216

Answer 2

\(58\times x-934=6722\)

\(\Rightarrow58\times x=6722+934=7656\)

\(\Rightarrow x=7656:58=132\)

Answer 3

\(2005+x\times34=5337\)

\(\Rightarrow x\times34=5337-2005=3332\)

\(\Rightarrow x=3332:34=98\)

Answer 4

\(2005+x\cdot34=5337\)

\(\Rightarrow34x=5337-2005\)

\(\Rightarrow34x=3332\)

\(\Rightarrow x=98\)

Answer 5

\(12\times x\times15=38880\)

\(\Rightarrow180\times x=38880\)

\(\Rightarrow x=38880:180=216\)

Answer 6

\(58\cdot x-932=6722\)

\(\Rightarrow58x=6722+934\)

\(\Rightarrow58x=7656\)

\(\Rightarrow x=132\)

Answer 7

\(12\cdot x\cdot15=38880\)

\(\Rightarrow180x=38880\)

\(\Rightarrow x=\frac{38880}{180}\)

\(\Rightarrow x=216\)
