Answer:
X=2
Step-by-step explanation:
y= 2x- 3
1/2x= 2x-3
1/2x-2x= -3
x-4x= 2*-3
-3x=-6
x=2
Answer:
20 and 16
Step-by-step explanation:
Let us find x and y.
x – y = 4 _____(1)
x/2 + y/2= 18___(2)
Multiply (2) by 2 and add to (1)
x - y = 4
+<u>(x + y = 36)</u>
<u>2x = 40</u>
=> x = 40 / 2 = 20
From (1):
20 - y = 4
=> y = 20 - 4 = 16
The two numbers are 20 and 16.

$
9
You add the money and the interest to get
$
99
for the first year. However, the next year is different. It's compound interest, so you have to multiply
10

108.90 i think lol
<span>2p + q = 1
9p + 3q + 3 = 0
q = 1 - 2p
replace </span>q = 1 - 2p into 9p + 3q + 3 = 0
9p + 3(1 - 2p) + 3 = 0
9p + 3 - 6p + 3 = 0
3p + 6 =0
3p = -6
p = -2
q = 1 - 2p
q = 1 -2(-2)
q = 1 + 4
q = 5
(-2 , 5)
answer
<span>{(-2, 5)} first one</span>
