Answer:
200
Step-by-step explanation:
Find 60 kilos then just follow the line up till you reach the blue line
Slope intercept form is : y = mx + b
x + y = 180
-x -x
y = -x + 180
y = -1x + 180
The slope intercept form is : y = -x + 180
(6x+9y=78) - (6x+4y=38) = (5y=40) = y=8
(2x+3(8)=26) = (2x+24=26) = (2x=2) = x=2
