Answer:
x=7
Step-by-step explanation:
AC=3x+3 AB=-1+2x and BC=11
AC = AB + BC
ALL THE STEPS:
3 X + 3 = - 1 + 2 X + 11
3 X + 3 = 2 X + 10
3 X + ( - 2 X ) + 3 = 2 X + ( - 2 X ) + 10
X + 3 = 10
X + 3 + ( - 3 ) = 10 + ( - 3 )
X = 7

m=money
w=weeks
280-130=150
150/6=25 this is how much she earns per week
25*2=50 this is how much she earned in two weeks

m=25w+80
plug in to check:
(25*2)+80=130
(25*8)+80=280
