Question

four times a larger number added to two times a smaller number is 15 the difference between the two numbers is 10 find the both the numbers

Answer 1

the the larger number be x
so the smaller number will be x-10
now
4x+2(x-10)=15
4x+2x-20=15
6x=20+15
x=35÷6
=5.8
the larger number is 5.8
and the smaller number is (5.8-10)=-4.16
