Answer:
x = 2, y= 3
Step-by-step explanation:
y = -2x+7
y = 5x-7
Since the equations are both equal to y, set them equal to each other
-2x+7 = 5x-7
Add 2x to each side
-2x+7 +2x= 5x+2x-7
7 = 7x -7
Add 7 to each side
7+7 = 7x
14 = 7x
Divide by 7
14/7 = 7x/7
2 = x
Now find y
y = 5x-7
y = 5*2 -7
y = 10-7
y =3
Answer:
3, 15/7, 9/7, 3/7, -3/7, -9/7
Answer:
x = 10
Step-by-step explanation:
We need to isolate X.
3x - 7 = x + 13
subtract 13
3x - 7 - 13 = x
combine like terms
3x - 20 = x
subtract 3x
- 20 = x - 3x
Combine like terms
- 20 = - 2x
Divide by -2
10 = x
Eliza started out with $324.18 on Jan. 18th and had outstanding cheques of $15.00+77.49+$124.28=$216.77. So her actual balance was $324.18-$216.77=$107.41. Now she has $487.38 so $487.38-$107.41=$379.97 balance for the deposited amount.
