Step-by-step explanation:
Using Simultaneous Equation
Substitution method
Recall
x+2y=13. equ.1
3x-5y=6. equ.2
equ.1=
x-2y=13
x=13-2y. equ.3
Substitute 'x' into equ.2
3(13-2y)-5y=6
39-6y-5y=6
39-11y=6
collect like terms
39-6=11y
33/11=11y/11
therefore y=3
Substitute 'y' into equ.1, equ.2 or equ.3
Recall equ.3
x=13-2y
x=13-2(3)
x=13-6
therefore x=7
x=7, y=3
