Numbers x and y.

The initial translation into symbols giving two equations:

Multiply both members of the fraction equation by 4*5.
15x+4y=220

System to solve is this one:

Subract four times the second from the first and solve for x value.

simplification of that

.

Now, find y.

To solve any word problems. All you need do at first is to introduce a variable. In this case, two numbers are given so the variables are two in number. Let the first and second number be x & y respectively. x+y=22 3x/4+y/5=11 solving simultaneously (x+y)=22 15x+4y=220 4*--(x+y)=22 15x+4y=220 4x+4y=88 15x+4y=220 subtracting -11x=-132 x=12 substitute x into the first equation x+y=22 12+y=22 y=22-12=10
