x = 6.5

Step-by-step explanation:


\sf 23 - 2x = 10

subtract 23 from both sides


\rightarrow \sf 23-2x-23=10-23

simplify the following


\rightarrow \sf -2x=-13

divide both sides by -2


\rightarrow \sf (-2x)/(-2)=(-13)/(-2)

simplify


\rightarrow \sf x=(13)/(2)

in decimals


\sf \rightarrow x = 6.5

Recheck the following


\hookrightarrow \mathrm{23 - 2(6.5) = 10}


\hookrightarrow \mathrm{23 -13 = 10}


\hookrightarrow \mathrm{10 = 10}

L.H.S = R.H.S thus. x = 6.5
