Answer:
a=-5
Step-by-step explanation:
subtract 3 from both sides
15=-3a
divide by -3
a=-5

Answer:
The solution of the equation 4x+y=5 and 3x+y=3 be (2 , -3) .
Option (D) is correct .
Step-by-step explanation:
As given the equations are .
4x+y=5
3x+y=3
Subtracted 3x+y=3 from 4x+y=5 .
Thus
4x - 3x + y - y = 5 - 3
x = 2
Put in the equation 4x+y=5 .
4 × 2 + y = 5
8 + y = 5
y = -8 + 5
y = -3
Therefore the solution of the equation 4x+y=5 and 3x+y=3 be (2 , -3) .
Option (D) is correct .
Answer:
PLACE VALUE
Step-by-step explanation:
To Find:in a multi-digit number, the number place that a digit is in determines it's?
Solution :
The number place that a digit is in determines it's PLACE VALUE
Definition of place value : Place value can be defined as the value represented by a digit in a number on the basis of its position in the number.
Thus in a multi-digit number, the number place that a digit is in determines it's PLACE VALUE.
Eg . 389
Since the digit 8 is on tens place
So, it makes us to determine its place value
Place value of 8 is 80
Hence in a multi-digit number, the number place that a digit is in determines it's PLACE VALUE.
