Use substitution to solve the system of equations. y=x + 1.74 4x-2y = 4

(3.75,0) (4,4) (3.75,5.5) (5.5,4)

y = 3.75+1.74 = 5.49=5.5 = 5.5

4 (3.75) - 2 (5.5) = 15 - 11 = 4

Step-by-step explanation:

y = x + 1.74 → - x + y = 1.74

(1/2) (4x - 2y = 4) → 2x - y = 2

Add two eq → x=3.74 and y=5.5

The problem says that u need replace but with the process before you can get the result easily.

y = 3.75+1.74 = 5.49=5.5 ≠ 0

4 (3.75) - 2 (0) = 15 ≠ 4

y = 4+1.74 = 5.74=6 ≠ 4

4 (4) - 2 (4) = 8 ≠ 4

y = 3.75+1.74 = 5.49=5.5 = 5.5

4 (3.75) - 2 (5.5) = 15 - 11 = 4

y = 5.5+1.74 = 7.24 ≠ 0

4 (5.5) - 2 (4) = 14 ≠ 4
