Marcos
20x+10y= 100----------1
Alicia
10x+20y= 110-------------2
solve 1 and 2
20x+10y= 100 X 1
10x+20y= 110 X 2
20x+10y= 100
-20x+40y= 220
-30y= -120
y= 120/30
y= 4
put y= 4 in 1
20x+10y= 100
20x+10(4)= 100
20x+40=100
20x=100-40
20x=60
x= 60/20
x=3
Answer:
First, you put the answer in slope intercept form,y=-7+4x. You substiuite which is going to be y-4x+4x=-7+4x. You simplify to y=-7+4x. You plug that into the other equation and solve. It turns out to be y= -59/9, and x=1/9. Hope this helps!
