#x=-15#

Explanation:

#"distribute the bracket"#

#x-2=-17#

#"add 2 to both sides"#

#xcancel(-2)cancel(+2)=-17+2#

#x=-15#

#color(blue)"As a check"#

Substitute this value into the left side of the equation and if equal to the right side then it is the solution.

#0.5(-30-4)=0.5xx-34=-17#

#x=-15#

Explanation:

#0.5(2x-4)=-17#

Double both sides

#2x-4=-34#

Add 4 to both sides

#2x=-30#

Divide both sides by 2

#x=-15#
