Answer:
10
Step-by-step explanation:
2x - 3y = 24 ------ (1)
3x + 4y = 2 ------ (2)
(1) × 4,
8x - 12y = 96 ------ (3)
(2) × 3,
9x + 12y = 6 ------ (4)
(3) + (4)
17x = 96 + 6
= 102
x = 102 ÷ 17
= 6
Sub x = 6 into (2),
3(6) + 4y = 2
18 + 4y = 2
4y = 2 - 18
= -16
y = -16 ÷ 4
= -4
Therefore,
x - y = 6 - (-4)
= 6 + 4
= 10

Answer:
3x^2-x+5x-10+9=3x^2+4x-1
Step-by-step explanation:3x^2-x+5x-10+9=3x^2+4x-1
Select the number line which shows that Danny has -5$ in his bank account
if Danny had 120$ and spends 125$ that's
120 - 125 = -5
so -5$
The denominator can't be equal to 0, so
Now we can solve the equation
