Question

Four times a number make three times a number added toghether make 43.two times the second number, subtracted from three times the first give 11.what are the numbers

Answer 1

$\sf \red{Answer}$

Supposed first number is X.

And another number is Y.

By first condition,

4X+3Y=43…. (1)

By second condition,

3X-2Y=11……(2)

Multiplying first by 2 and second by 3.

8X+6Y=86

+9X-6Y=33

We get, 17X=119

I. E. X=119/17

X=7

Substitute X=7 in equation 1 st .

28+3Y=43

3Y=43–28

3Y=15

Y=5.

This number are (7,5) .
