Answer:

#s=3#

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"#
