What is the value of y in 3y + 3 = 30

9

Step-by-step explanation:

first thing you do is take +3 to the other side of the equality sign which makes it 30-3 , which gives 27

Then you would have "3y=27 you would further go on to divide both sides by 3 which gives y=9

b

step-by-step explanation:

the word superfluous means unnecessary

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
