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
