<span>In the case of linear equations with two unknowns, you would have two solutions: and "X" value and a "Y" value
-2x - 3y = 7
-0.4x - 0.6y = 1.4
In this case the solution is x=4 and y=-2

2 gallons 25% of 4 is 1 so there is about 1 gallon of pure in there no so adding two will make 3 gallons of antifreeze bringing total to 6 gallons 3/6 = .5 boom bam 50%
C. 1.07p
1.00 is for 100% of the cost and the .07 is for the tax.
Answer:
Look at image
Step-by-step explanation:
well y-4=3(x+5)
distribute the 3 to x and 5 --> y-4 = 3x+15
now add 4 to both sides --> y-4+4 = 3x + 15 +4
y= 3x + 19
