Question

The sum of 3 times a number and 9 equals 4 use the variable b for the unknown number write in an equation​

Answer 1

Answer: b= -5 over 3

Explanation:

create the equation 3b + 9 = 4

subtract 9 from each side to isolate the variable

we are left with 3b = -5

to further isolate the variable divide by 3

3b/3 = -5/3

3b divided by 3 is b, which is equal to -5 divided by 3; -5/3

b = -5/3 is your answer
