Answer 3

so this mean that calcule the x ,for example from the first equation and substitute this result value of x in place of x in second equation and hence will can calcule easy the value of y

ok ?

Answer 4

i took 5x-1(2x+3)=-3 and then i did the work and for x i got 0 is that right so far?

Answer 5

so

5x-2x-3=-3
3x=0
x=0

yes is right

Answer 6

and now you need to calcule the y value

Answer 7

so 5(0)-y=-3
0-y =-3
-0 -0
-y=-3 so the anwser is y=3

Answer 8

y=3 is right

so do you understand it sure right ?
