Answer:
Enter it into Desmos!
Step-by-step explanation:
3x-4y-8=12
first combine like terms
3x-4y=12+8
then isolate on variable
3x=20+4y
now divide by three to find x
x=20/3+4/3 x=8
to find y plug in x to the original equation
3(8)-4y-8=12
24-4y=20
-4y=20-24
-4y=-4
y=1
Y=5x-7 -3x-2y=-12 (2,3)
y=4x+3 y=-x-2 (-1,-1)
12x+8y=140 5 adults 10 children
12(5)+8(10)=140
60+80=140
