Answer: x= 3.75 , y =6.50
Step-by-step explanation:
Let cost of tacos = x
Let cot of enchilada = y
ATQ
4x + y = 21 . 50. (Eq 1)
2x +3y = 27. (Eq 2)
Multiply( eq 1 ) by 3
(4x + y =21 .50) × 3
12x +3y = 64 .50. (Eq 3)
Subtacting (eq 2) from (eq 3 )
12x + 3y = 64 .50
-( 2x +3y = 27 .00)
10x = 37.50
X = 37.50/10
X = 3.75
Putting value of x in( eq 1)
4 ×( 3.75) +y = 21.50
15 +y = 21.50
Y = 21.50 - 15
y = 6.50
