Answer:
x = 4, y = 1 is the solution of the given system of equation.
Step-by-step explanation:
Here, the given set of equations is:
3 x + 2 y = 14
x + y = 5 ⇒ y = 5- x
Solve the given system by SUBSTITUTION METHOD:
Substitute the value of y = 5- x in 3 x + 2 y = 14 , we get
3 x + 2 y = 14 ⇒ 3x + 2 (5- x) = 14
or 3 x - 2x + 10 = 14
⇒ x = 10+ 14 = 14 - 10
or, x = 4
Now, y = 5 - x = 5- 4 = 1
Hence, x = 4, y = 1 is the solution of the given system of equation.
Answer:

Answer: 108
Step-by-step explanation:
x = 108
The number is 16
16/4 = 4
16 - 12 = 4 (true)
your number is 16 hope this helps
1.a.
3 1/3 - 2 5/6 =
= 10/3 - 17/6
= 20/6 - 17/6
= 3/6 = 1/2
1.b.
1/2 * 3 1/3 + 1/2 * 2 5/6 =
= 1/2 * 10/3 + 1/2 *17/6
= 10/6 + 17/12
= 20/12 + 17/12
= 37/12
= 3 1/12
2.a.
2 1/3 - 1 1/2 =
= 7/3 - 3/2
= 14/6 - 9/6
= 5/6
2.b.
1/12 * 5/6 = 5/72
3.
3 3/8 * 3 =
= 27/8 * 3/1
= 81/8
= 10 1/8
4.
6 1/4 - 5 1/2 =
= 25/4 - 11/2
= 25/4 - 22/4
= 3/4
(3/4)/(6 1/4) =
= (3/4)/(25/4)
= 3/4 * 4/25
= 3/25
