Q:

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)

Accepted Solution

A:
Answer:y = 3.75+1.74= 5.49=5.5 =5.54(3.75) - 2(5.5) =15 - 11 =4Step-by-step explanation:                                            y = x+ 1.74 →  -x + y = 1.74  (1/2)(4x - 2y = 4) → 2x - y = 2Add two eq → x=3.74 and y=5.5The 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 ≠ 04(3.75) - 2(0) =15 ≠ 4y = 4+1.74= 5.74=6 ≠ 44(4) - 2(4) =8 ≠ 4y = 3.75+1.74= 5.49=5.5 =5.54(3.75) - 2(5.5) =15 - 11 =4y = 5.5+1.74= 7.24 ≠ 04(5.5) - 2(4) =14 ≠ 4
