-10x+5=-6x-35 Add 6 both sides -10x+5=6x-35 Combine -10x and 6x to get -4x 4x+5=-35 Subtract 5 from both side -4x = -35-5 Subtract 5 from -35 to get -40 -4x=-40 Divide both side by 4 -4/-40 Divide -4 and -40 will give you 10 x = 10
Yes she would be right as for how i got the answer first i started by using 15 hours as 100% then i times fifteen by 20% which gave me three hours then add three hours to fifteen and it gave me 18. so she worked 120% more than last week hoped that helped
