Answer: y = 2 x = -2
Step-by-step explanation:
-x + y = 4
x + 3y = 4
Since x and -x are opposite, we can use the system of elimination
To do that, we add the first equation and the second equation together
-x + y = 4
+
x + 3y = 4
↓
4y = 8
Now we solve for y
4y = 8
Divide both sides by 4
y = 2
Since we now know y, we can solve for x by substituting y for 2 in one of the equations.
x + 3y = 4
Substitute y for 2
x + 3 (2) = 4
x + 6 = 4
Subtract 6 from both sides
x = -2
Hope I helped! And sorry if I repeated somethings.
