How do i put this in standard form. ax+by=c

3x - 4y = 18

multiply all terms in the equation by the lowest common multiple of 2 and 3, the denominators of the fractions. The lowest common multiple is 6

6 × x - 6 × y = 6 × 3

3x - 4y = 18 ' in standard form '

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).

hope i
