4 mangoes and 5 apples cost $4.70. 1 mango and 2 apples cost $1.40 find the cost of 1 mango and 1 apples

Let the price of mangoes be x and the price of apples be y

4x+5y = 4.70 ---- (1)

x+2y=1.40 ---- (2)

1- 2*(2): 2x + y =1.90 ---- (3)

2*(3) - (2) : 3x = 2.40

x = 0.80 ---- (4)

Subst. (4) into (2),

0.80 + 2y =1.40

2y = 0.60

y = 0.30

x + y = 1.10

The cost of 1 mango and 1 apple is $1.10
