Explanation:
#"distribute the bracket on the left side of the equation"#
#-4x+8-8x=-22-10x+30larrcolor(blue)"simplify both sides"#
#rArr-12x+8=-10x+8#
#"collect terms in x on the left and numeric values on the right"#
#"add 10x to both sides"#
#-12x+10x+8=cancel(-10x)cancel(+10x)+8#
#rArr-2x+8=8#
#"subtract 8 from both sides"#
#-2xcancel(+8)cancel(-8)=8-8#
#rArr-2x=0rArrx=0" is the solution"#
