What are the intercepts of -4x 6y-5z=60

X intercept is when y and z=0
yinter cept is when x and z =0
zintercept is when x and y =0

set to zero and solve

xint
-4x+6(0)-5(0)=60
-4x=60
divide -4
x=-15
xint is (-15,0,0)

ying
-4(0)+6y-5(0)=60
6y=60
divide by 6
y=10
yint is (0,10,0)

zint
-4(0)+6(0)-5z=60
-5z=60
divide by -5
z=-12
zint is (0,0,-12)

xint is (-15,0,0)
yint is (0,10,0)
zint is (0,0,-12)

10 will be the number of adult tickets and 11 will be the number of children tickets. i hope i could ! good luck : )
