the answer would then be (x, y)Question 2.You use the same process but now you plug the second equation in for x:5y - 16 + 5y =4Hope this helps ^^-1 rewrite the equations as 7x + y = 13-2x + y = -.5If you subtract the second equation from the first you get9x = 13.5x = 1.5Substitue x = 1.......
lol you need to do it on your own XD
Question 1.
The easiest way is to use the use the second equation. SInce it's already solved for "y", you just need to plug it in the first equation.
it would look like this:
7x + 2x - 0.5 = 13
after that you can solve for "x"
once you get "x", you take that number and plug it in any of the two equations. With this you can get "y".
the answer would then be (x, y)
Question 2.
You use the same process but now you plug the second equation in for "x":
5y - 16 + 5y =4
Hope this helps ^^

1).
7x + y = 13
y = 2x - 0.5
2x - y = 0.5
9x = 13.5
x = 1.5
y = 2.5
2).
x + 5y = 4
x = 5y - 16
10y - 16 = 4
y = 2
x = -6
