The solution to the system of linear equations is: (−5, −11).
<h3>What is the Solution to the System of Linear Equations?</h3>
The solution to a system is the x and y -coordinates that satisfies the two linear equations.
Given the linear equations:
Line A: y = x − 6
Line B: y = 3x + 4
Now, equating these two equations
x - 6 = 3x + 4
2x = -10
x = -5
y = -11
Hence, the solution is: (−5, −11), because the point satisfies both equations.

79 dollars plus its 40% times 4 equals 442.4 that plus 12% equals 495.488 rounded up to 495 dollars and 49 cents
<u>Answer:</u>
16.4%
<u>Step-by-step explanation:</u>
We know that a station charges $15.95 for a lubrication job and as a promotion sell six coupons were sold for lubrication jobs for $80.
We are to find the percentage discount that was being offered on purchase of 6 coupon lube book.
Original price of 6 coupons = 6 × 15.95 = $95.7
Difference in prices = 95.7 - 80 = $15.7
Percentage discount = 15.7/95.7 = 16.4%
Method 1:
Convert the mixed number to the improper fraction:
Make the product:
<em>canceled 2</em>
Method 2:
<em>use the distributive property a(b + c) = ab + ac</em>
