Question

Five times a number and four times another number added together give 47 . Four times the first number and five times the second number added together is 43 . Find the numbers ?
​

Answer 1

Answer:

i) 5x+4x=47

9x=47

x=47÷9

x= 5.22

5x=5×5.22

= 26.1

4x=4×5.22

= 20.88

ii) 4a+5a=43

9a=43

a= 43÷9

a=4.77

4a=4×4.77

=19.08

5a=5×4.77

=23.85

Answer 2
