The solution to given system of equations is 
The given equation has one solution
<em><u>Solution:</u></em>
Given system of equations are:
12x - 13y = 5 --------- eqn 1
x = 23y + 10 --------- eqn 2
We have to solve the system of equations by substitution
<em><u>Substitute eqn 2 in eqn 1</u></em>
12(23y + 10) - 13y = 5
276y + 120 - 13y = 5
263y = 5 - 120
263y = -115
<em><u>Substitute the above value of "y" in eqn 2</u></em>
Thus the solution to given system of equations is
Thus the given equation has one solution
Answer: When you divide two integers with the same sign, the result is always positive. Just divide the absolute values and make the answer positive. When you divide two integers with different signs, the result is always negative.
Step-by-step explanation:
The number of chicken wings that Mohal can buy is 12.
<h3>How to calculate the cost?</h3>
It should be noted that Mohal bought 20 chicken wings for $50.00. The cost of each wing will be:
= Total amount / Number of chicken wings
= $50 / 20
= $2.50
When he spent $30.00, the number of wings will be:
= Amount / Cost per wing
= $30 / $2.50
= 12
There will be 12 chicken wings. This illustrates the proportion.
