Solve the system of equations algebraically.
andrew11 [14]

Answer: d. (17, 20)

Step-by-step explanation:

We have the following system of equations:

x-3y=8 (1)

5x-4y=5 (2)

Isolating x from (1):

x=\frac{8+3y}{4} (3)

Substituting (3) in (2):

5(\frac{8+3y}{4})-4y=5 (4)

Isolating y:

\frac{40}{4}+\frac{15 y}{4}-4y=5 (5)

10-5=4y-\frac{15 y}{4} (6)

y=20 (7)

Substituting (7) in (1):

x-3(20)=8 (8)

Isolating x:

x=17 (9)

Hence, the correct option is d. (17, 20)
