There are 6 pencils in each pencil box. There are 3 pencil boxes. How many pencils are there in total?
Equation of a line in standard form is Ax + By = C
A is a pos. integer and B + C are integers
1) multiply all terms in the equation by 2
2y = x - 6
2) subtract 2y from both sides
2y - 2y (cancelled out) = x - 2y - 6
x - 2y - 6 = 0
3) add 6 to both sides
x-2y = 0 +6 (-6 and +6 cancel out)
therefore,
x - 2y = 6
is the equation in standard form

Answer:
71
Step-by-step explanation:I think I solve it a weird way but here it is.
70 times 5= 350
65+68+66+80= 279
350-279= 71
Check:
65+68+66+80+71= 350
350/5=70 which means 71 is the correct answer
