Answer:
y=22h+18, where h is the working hour, y is the charge
Step-by-step explanation:
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:
1 = The Value of the expression is 10 for x = 3 and y = 2
2 = The Value of the expression is 10 for x = 3 and y = 2
3 = The Value of the expression is 10 for x = 2 and y = 3
4 = The Value of the expression is 10 for x = 2 and y = 3
5 = The Value of the expression is 10 for x = 2 and y = 3
6 = The Value of the expression is 10 for x = 3 and y = 2
