Question

a) 20 - (x +1) =10.

b)  6 +10x = 4^7 : 4^5 .

Answer 1

a) \(20-\left(x+1\right)=10\)

\(\Rightarrow x+1=20-10\)

\(\Rightarrow x+1=10\)

\(\Rightarrow x=10-1\)

\(\Rightarrow x=9\)

b) \(6+10x-4^7:4^5\)

\(\Rightarrow6+10x=4^{7-5}\)

\(\Rightarrow6+10x=4^2\)

\(\Rightarrow6+10x=16\)

\(\Rightarrow10x=16-6\)

\(\Rightarrow10x=10\)

\(\Rightarrow x=\dfrac{10}{10}\)

\(\Rightarrow x=1\)

Answer 2

a: =>x+1=20-10=10

=>x=9

b; =>10x+6=16

=>10x=10

=>x=1

Answer 3

a,  x + 1 = 20 - 10

     x+ 1= 10

     x= 10-1

     x= 9

b,6 +10x = 4²

   ^{6 + 10X = 16}

   ^{10X = 16 - 6}

     ^{10X = 10}

      ^{X= 10 : 10}

     ^{X= 1}
