When three times a number is subtracted from 20, the result is 4 plus the number. What is the number? equation. 20 - 3n= 4 +n (T
ype an integer or a decimal.) Next, solve the equation. Begin by isolating the constants on one side of the equation and the variables on the other. To move the variables to the right side of the equation, add 3n to both sides. 20-3n = 4+n
1 is the whole number which means it goes before the decimal point. 2/10 is the fractional piece making it go after the decimal point in the tenths place.
