Question

True or False: (1, 3) is a solution to the system of linear equations shown

below.
y= 4x - 1
y = x + 2

Answer 1

True

Explanation:

You can substitute x = 1 and y = 3 into both equations and see if it's true or not.

y = 4x - 1

becomes

3 = 4(1) - 1

3 = 4 - 1

3 = 3

True

y = x + 2

becomes

3 = 1 + 2

3 = 3

True

Since both equations come out true, this (1, 3) is a solution.

Answer 2

True

Explanation:

(1, 3) is a solution to the system of linear equations shown is true
