Answer:

x= 0.5 y=11

Step-by-step explanation:

solve like simultaneous equations

[tex](10x + y = 16) + ( - 10x + 5y = 50)[/tex]

(adding the equations together as that is how you get rid of the x values)

so you are left with 6y= 66

y=11

now substitute y into one of the equations (doesn't matter which)

10x + 11= 16

10x= 5

x=0.5
