Which value of a from the set (16,18,20,22) makes the equation 2(42-a)=48 true

Steps to solve:

2(42 - a) = 48

~Distribute left side

84 - 2a = 48

~Subtract 84 to both sides

-2a = -36

~Divide -2 to both sides

a = 18

Best of Luck!

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
