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:
gm
Step-by-step explanation:
First, subtract 30x from each side to get:
-60 = -10x
Then, divide each side by -10 to get:
x = 6
Now, plug back in to check your answer:
30(6) - 60 = 20(6)
180 - 60 = 120
120 = 120
Hope this helps!! :)
Answer:
1) area = (x + 3)(2x + 3) ft²
2) 299 ft²
Step-by-step explanation:
<u>Question 1</u>
Area of a rectangle = width x length
Given:
- width = x + 3
- length = 2x + 3
⇒ area = (x + 3)(2x + 3) ft²
<u>Question 2</u>
If x = 10:
⇒ area = (10 + 3)(2(10) + 3)
= 13 · 23
= 299 ft²
