x²+y³=23
=>x+y³=23/2
=>x+y³=11.5
11.5/2
=5.75
so the first number is 5.75
now to find the seconfmd number just simply suntract the whole number whith the first number and the whatever you get divide it by 3 .
so let's do it.
23-11.5=11.5
=11.5/3
=3.83333
hence the first number is 5.75 and the second number is 3.83333
5.75×4=23
41-23=18
so now let me elaborate it by replacing the veriable with numbers ok.
5.75×2+3.83333×3=23
=11.5+11.5=23
5.75×4+3.8333×5=41
23+18=41
