girls = y

total= 70

x+y= 70. ---–----(1)

2x+ 3y=180---------(2)

(2)-2×(1)

2x+3y=180

_2x+2y=140

y= 40

x = 70-40=30

Answer 2

The number of boys are 30.

Step-by-step explanation:

Consider the provided information.

Let x represents the number of boys and y represents the number of girls.

Total number of boys and girls are 70.

$x+y=70$

$x=70-y$   ......(1)

Each boy gets 2 and each girl gets 3 oranges and the total number of oranges are 180.

$2x+3y=180$   ......(2)

Substitute the value of x in equation 2.

$2(70-y)+3y=180$

$140-2y+3y=180$

$y=40$

Substitute the value of y in equation 1.

$x=70-40$

$x=30$

Hence, the number of boys are 30.
