Answer:
Multiply equation by 5 and
by 4
Step-by-step explanation:
Given:
Equations are
To find: constant by which each equation should be multiplied to eliminate the variable in the given system of equations
Solution:
Multiply equation (i) by 5 and (ii) by 4 to get the following equations:
On subtracting these equations, we get
So, the variable gets eliminated
In order to divide integers, the first thing to check is the sign:
- When dividing two positive integers, the result will be a positive integer.
- When dividing two negative integers, the result will be a positive integer.
- When dividing integers with different signs (one negative and one positive), the result will be a negative integer.
Then, after checking the sign, we need to calculate the value of the division.
Some examples of divisions are:
In the first division, the result is 3, because we have that 8 * 3 is equal 24.
Also, both numbers are positive, so the result is also a positive number.
In the second division, the result is -3, because 5 * (-3) is equal -15.
The result is negative, because the two numbers have different signs.
In the third division, the result is 10, because -10 * 10 is equal -100.
The result is positive, because both numbers are negative.
