Answer:
A = 217
B = 45
Step-by-step explanation:
A+B = 262
A - B = 172
A = 172 + B
172 + B + B = 262
2B = 90
B = 45
A = 172 + (45)
A = 217

Answer:
3 30 page printers, 10 70 page printers
Step-by-step explanation:
x + y = 13
40x+70y = 820
Solving for y in first equation gives: y = 13 - x
Plug into second equation: 40x + 70(13 - x) = 820
40x + 910 - 70x = 820
-30 x = -90
x = 3
Plug into original equation: 3 + y = 13
y must = 10.

Well from what i see this equation isn't a point at all, however it does start at (0,0)
Answer:
2x-5= -20
move -5 to the other side
sign changes from -5 to 5
2x-5+5= -20+5
2x= -15
divide by 2 for both sides
2x/2= -15/2
cross out 2 and 2, divide by 2 and 2 and then becomes x
x= -15/2
