When three times a number is subtracted from 13 the result is 5 plus the number what is the number?

There is no graph but what i can say is that 1 is the slope and that -2 is the y- intercept

When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. if you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.
