Question

6(2x+2³)+40=100

Answer 1

\(6\left(2x+2^3\right)+40=100\)

\(=>6\left(2x+8\right)=100-40=60\)

\(=>2x+8=60:6=10\)

\(=>2x=10-8=2\)

\(=>x=2:2=1\)

Answer 2

\(6\left(2x+2^3\right)+40=100\)

\(\Rightarrow6\left(2x+8\right)=100-40\)

\(\Rightarrow6\left(2x+8\right)=60\)

\(\Rightarrow2x+8=60:6\)

\(\Rightarrow2x+8=10\)

\(\Rightarrow2x=10-8\)

\(\Rightarrow2x=2\)

\(\Rightarrow x=1\)
