To solve, set an equation:
472=0.8x
Divide both sides by 0.8
472/0.8=0.8x/0.8
x=590
Answer: The original price was $590
X= 77 degrees
hope it helps
2x + 3y = 6
-2 -2
3y = -2x + 6
Divide by 3 on all sides:
y = -2/3x + 2
Answer - y = -2/3x + 2
x - 3y = 9
-x -x
-3y = -x + 9
Divide by -3 on all sides:
y = 1/3x - 3
Answer - y= 1/3x - 3
Hope this Helps!!
