Answer:
x=2 y=-10
Step-by-step explanation:
14x =-22-5y eq---1
5x= 6 =5y eq --- 2
Subtract eq 1 from eq 2 we get the value of x
x= 2
put x = 2 in equation 1
14 x = -22 - 5y
14 (2) = -22 - 5y
28 =-22 - 5y
+22 =-5y
50 = -5y
y= - 50/5
y = - 10
1. (4)x + y =50
2x + 4y =172
2. (1)x + y =8
150x + 50y =800
3. (1)x + y =20
25 + 10y =290
Just trust me and its too much work explaining and im lazy so just ask your teacher or a friend if you can.
