Question

What is the solution to the system of the equations?

x = y - 3

x + 3y = 13

Answer 1

Answer:

Solution (1, 4)

Step-by-step explanation:

x = y - 3

x + 3y = 13

Substitute x = y - 3  into x + 3y = 13

y - 3  + 3y = 13

4y - 3 = 3

4y =16

y = 4

Substitute y = 4 into x = y - 3

x = 4 - 3

x = 1

Solution (1, 4)
