= - 6 + 2
= - 4
What is the sum of two numbers is 32 and their quotient is 3 what is the answer?
2 answers:
Answer:
The numbers are 24 and 8.
Step-by-step explanation:
1. Let´s name the numbers as follows:
x=first number
y=second number
2. As the sum of the two numbers is 32, you have the first equation:
(Eq.1)
3. As the quotient of the two numbers is 3, you have the second equation:
(Eq.2)
4. Solving for x on Eq.2:
5. Replacing Eq.3 in Eq.1:
6. Replacing the value of y in Eq.3:
Therefore the numbers are 24 and 8.

Answer:
Each shirt cost $<u>7</u> and each pair of shorts cost $<u>17</u> .
Step-by-step explanation:
let shirts be represented as x
let shorts be represented as y
Younger brother spent $79 on 4 new shirts and 3 pairs of shorts.
4 x + 3 y = $79 .......equation 1
Older brother purchased 7 new shirts and 8 pairs of shorts and paid a total of $185.
7 x + 8 y = $185 .......equation 2
multiply equation 1 by 7 and equation 2 by -4 and add both equations to get the value of y.
7 × (4 x + 3 y = $79) ⇒ +28 x + 21 y = $553
-4 × (7 x + 8 y = $185) ⇒ <u> -28 x - 32 y = - $740</u>
0 - 11 y = - $187 ⇒ -11 y = - $187
y = ⇒ y = $17
shorts = y = $17
put value of y in equation 1
4 x + 3 ( $17 ) = $79 ⇒ 4x + $51 = $79 ⇒ 4x = $79 - $51
4x = $28 ⇒ x = ⇒ x = $7
Shirts = x = $7
