My sister needs help!

1 answer:

3 0

Idk if she's too young to learn cross multiply, but this is an easier method.

Multiply everything by 4 which cancels out the 4 on the left side.
36z-16/5 <= 7z + 2
Now multiply everything by 5, cancelling out the right side 5.
36z-16 <= 35z + 10
Solve the equation normally
z-16<=10

z<=36
