Explanation:
#"distribute bracket on right side of equation"#
#8=2s+4-2#
#rArr8=2s+2#
#"subtract 2 from both sides"#
#rArr6=2s#
#"divide both sides by 2"#
#rArrs=3#
#color(blue)"As a check"# Substitute this value into the right side and if equal to the left side then it is the solution.
#"right "=2(3+2)-2=(2xx5)-2=10-2=8#
#rArrs=3" is the solution"#
