Answer:
(2.5, -1/2)
Step-by-step explanation:
Solve the system by substitution 3x-y=8 and x+y=2
lets look at x + y =2
rewrite it as x = 2 - y
so now x is 2- y so we can substitute it in
3(2-y) -y = 8 this is the equation rewritten with x as 2-y, now solve for y
6 -3y - y =8
-6 -6
-4y = 2
/-4 /-4
y = -1/2
so now remember x = 2 - y
use our new y
x = 2 - (-1/2)
x = 2 + 1/2
x = 2 and 1/5 or 2.5
