Answer:
[tex]x = 10[/tex] will make the equation true
Step-by-step explanation:
Given
[tex]\{3,10,90,108\}[/tex]
[tex]3x +3= 33[/tex]
Required
Which is true for x
We have:
[tex]3x +3= 33[/tex]
Collect like terms
[tex]3x= 33 - 3[/tex]
[tex]3x= 30[/tex]
Solve for x
[tex]x = 30/3[/tex]
[tex]x = 10[/tex]
