Evaluate 0.3y + y/z =10 and z =5

So since z=5 you are going to substitute z in the equation with 5. So it should look like 0.3y+y/5 = 10. So in this problem I assume you are solving for y so you will divide on both sides of the equation. So 0.3y/ 0.3 cancels out and you are left with y/5=10/0.3 so 10/ 0.3 is 33.3333333333. Now you are left with y/5=33.3333333333 . Now didvide 5 on both sides. Y should equal 6.66666666667. This was tricky. Hoped that helped !!!
