Question

Determine if the given ordered pairs are solution of x+ 4y = 7.

1. (3,1) 2.(2,1)




Solutions:​

Answer 1

(3, 1 ) is a solution

Explanation:

To determine if the given points are solutions, substitute the x and y values into the left side of the equation and if equal to the right side then they are solutions.

(3, 1 )

3 + 4(1) = 3 + 4 = 7 = right side , then a solution

(2, 1 )

2 + 4(1) = 2 + 4 = 6 ≠ 7 ← not a solution
