Answer:
The value of x for equation is 3.4
The value of y for equation is 5.2
Step-by-step explanation:
Given as :
The two linear equation are
2 x + y = 12 ........A
4 x - 3 y = 2 .........B
Now, Solving both equations , we get
3 × ( 2 x + y ) + (4 x - 3 y) = 3 × 12 - 2
Or, 6 x + 3 y + 4 x - 3 y = 36 - 2
Or, (6 x + 4 x) + (3 y - 3 y) = 34
Or, 10 x + 0 = 34
∴ x =
i.e x = 3.4
So, The value of x for equation , x = 3.4
Put the value of x into eq A
∵ 2 x + y = 12
Or, y = 12 - 2 x
Or, y = 12 - 2 × 3.4
Or, y = 12 - 6.8
∴ y = 5.2
So, The value of y for equation , y = 5.2
Hence, The value of x for equation is 3.4 and The value of y for equation is 5.2 Answer
The expression which is equal to the m times, m times, m times, m times, m rewritten in exponential form as,
The exponent or power of a number represent the multiplication of the that number to the power times.
Let suppose a number 2 has the power 2. Then it will be equal to,
Similarly, 3 times of number 2 equal to the number 2 with exponent 3.
The expression is m times, m times, m times, m times, m. It can be written as,
The number m is total 5 time multiply by itself. Thus, the exponential form of the above equation is,
The expression which is equal to the m times, m times, m times, m times, m rewritten in exponential form as,
