6x+3=45

6x+3-3=45-3

6x= 42

Divide by 6 for 6x and 42

6x/6= 42/6

x= 7

Check answer by using substitution method

6x+3= 45

6(7)+3= 45

42+3= 45

45= 45

The answer is x= 7

Describe a real world situation that is modeled by dividing two fractions or mixed numbers

Oduvanchick [21]

Hey there!
If you have a granola bar, and you've already eaten half of it and your 4 friends come up to you asking for equal pieces, you'd have to divide 1/2 by 4 to ensure that they each get an equal amount, or 1/8 of the bar.
Hopefully this helps!
