Answer:
x=9, y=3
Step-by-step explanation:
-4x+6y=-18
y=-2x+21
-4x+6(-2x+21)=-18
-4x-12x+126=-18
144=16x
x=9
y=-2x+21
y=-18+21
y=3
The answer is C) collateral

Answer:
Length BC = 26
Step-by-step explanation:
Perimetre = 94
; Perimetre = 2(2x + 3) + 2(3x - 1)
; 94 = 4x + 6 + 6x - 2
; 94 - 4 = 10x
; 90 = 10x
;Therefore the value of x = 9....Hence the length of BC
BC = 3(9) - 1
; BC = 26
