Answer:
y = -5/3x + 4/3z
Step-by-step explanation:
5x + 3y = 4z
3y = -5x + 4z
y = -5/3x + 4/3z
Answer:
x < 4
Step-by-step explanation:
Step 1: Write inequality
5x < 20
Step 2: Solve for <em>x</em>
- Divide both sides by 5: x < 4
Here we see that any number less than 4 will work. So numbers like 3, 0, or even -12587235897 would work.

You need one equation for the physical nickels and dimes, which total to 21:
n+d=21
Secondly, you need one equation for the numerical value of those nickels and dimes. We know nickels are worth $0.05 and dime are worth $0.10:
.05n+.1d=1.70
