Answer:
x=4
Step-by-step explanation:
(-x+3)-(x-5)=2x+8
(-x+3)+(-x+5)=2x+8
-x+3-x+5=2x-8
-2x+8=2x-8
-2x-2x=-8-8
-4x=-16
x=-16/-4
x=4

Answer:
(x, y) = (2 2/9, -1 4/9)
Step-by-step explanation:
Equate the values of y and solve for x.
1/4x -2 = -2x +3
(2 1/4)x = 5 . . . . . . . . add 2+2x to both sides
x = 20/9 = 2 2/9 . . . multiply by 4/9
y = -2(2 2/9) +3 = -4 4/9 +3 . . . . substitute for x in the second equation
y = -1 4/9
The solution is x = 2 2/9, y = -1 4/9.
