Answer:
23x = -115
Step-by-step explanation:
In the substitution method, you must solve for 1 variable in 1 equation to replace it in the other equation. For the system:
2x - 7y = 4
3x + y = -17
Solving for y in the second equation:
y = -17 - 3x
Replacing y in the first equation:
2x - 7(-17 - 3x) = 4
2x + 119 + 21x = 4
23x = -115
This is the new equation after use the substitution method.

Answer:
Yes, they are.
Step-by-step explanation:
<h3>1st rate)</h3>
Lets simplify both rates to the rate typer per minute.
(m is minutes)
3m = 96
Divide both sides by 3:
![\frac{3m}{3} = \frac{96}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B3m%7D%7B3%7D%20%3D%20%5Cfrac%7B96%7D%7B3%7D)
m = 32
So the rate is 32 words per minute.
<h3>2nd rate</h3>
5m = 160
Divide both sides by 5:
![\frac{5m}{5} = \frac{160}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B5m%7D%7B5%7D%20%3D%20%5Cfrac%7B160%7D%7B5%7D)
m = 32
<h3>So because the rates per minute are the same, they are equivalent.</h3>
