Answer:
Step-by-step explanation:
10x+ 150=220 is the equation for the second plan you subtract 150 from 220 to get 70 and divide that by 10 and you get 7 which is the number of weeks it'll take
220/25=x
So for this one it'll take 8.8 weeks to get enough money and you divide 220 by the amount which is 25 to get 8.8 the number of weeks I'll take
I dont understand what the second one is asking so sorry dude but I think that's right
Sum means add
difference means subttract
x+y=1
x-y=11
add the 2 equations together
2x+0y=12
divide 2
x=6
subitute
6+y=1
subtract 6
y=-5
x=6
y=-5
