Question

Solve the system of linear equations using the substitution method.

X = 5 and 2x + y = 10

A. (5, -5)

B. (5, 0)

C. (2, -2)

D. (2, -1)

Answer 1

B

Step-by-step explanation:

x = 5

2x + y = 10

Substitute x = 5 into 2x + y = 10

2(5) + y = 10

10 + y = 10

y = 0

Hence, coordinates are (5,0).
