4,165 because you have to subtract the 4200 and 35 because when you read the word problem it says difference which means subtract
A system that will produce infinitely many solutions will have the property where all the equations overlap. That means they will have the same slope and y-intercept.
An easy way to determine if they will produce infinitely many solutions is to put all the equations into

form. If everything is the same, you know it will have infinite solutions.
Solve for x by cross multiplying
Exact form: x= 191/7
Decimal form :x=27.28571428
Mixed number form:x=27 2/7
Its -1.5 or in other fraction form its -1 1/2.......hope that helps
Answer:
a = - 4, b = 5
Step-by-step explanation:
Expand the left side, then compare the coefficients of like terms.
- 3(2x² + ax + b)
= - 6x² - 3ax - 3b, compare to - 6x² + 12x - 15
Compare coefficients of x- terms
- 3a = 12 ( divide both sides by - 3 )
a = - 4
Compare constant terms
- 3b = - 15 ( divide both sides by - 3 )
b = 5
