What is the difference? (-4x + 3) - (7x - 3x^2 -1)

4x-6y-7x+8 combine like terms: -3x-6y+8 If all you want to do is simplify, then that is the final answer. However if we want to evaluate that when x=5 and y=2, we substitute (5) in place of x and (2) in place of y -3x-6y+8 -3(5)-6(2)+8 Then do all the operations: -15-12+8 -19

What is the question ehre

200 miles.45 x 3 (charge per day times days)135$205$ - 135$ = 70$0.35x = 70divide both sides by 0.35200
