Q: using the Substitution Method, and the value ory in

Mathematics
1 answer:
GenaCL600 [577]2 years ago
5 0

Answer:

Step-by-step explanation:

To properly apply the substitution method, it will be better for us to rearrange the system of equations to have similar variables on the same side

44 - 4 = -2y ----equation 1

10 = 7x + 4y --- equation 2

We can simply evaluate equation 1 to have

40 = -2y\\y = 40/-2 = -20\\

y = -20

From the first equation alone, we can evaluate the value of y as -20. This is because only one unknown is present in equation one, hence a single equation is sufficient enough to evaluate it. If to unknowns were present, the two equations would have been utilized to evaluate the solution.
