Answer:

q = 6

Explanation:

This 2-step equation is solved by ...

  • add the opposite of the unwanted constant:

3q -5 +5 = 13 +5

3q = 18

  • divide by the coefficient of the variable

3q/3 = 18/3

q = 6

Hey there!


3q - 5 = 13

ADD 5 to BOTH SIDES

3q - 5 + 5 = 13 + 5

CANCEL out: -5 + 5 because it gives you 0

KEEP: 13 + 5 because it help solve for the q-value


NEW EQUATION: 3q = 13 + 5


SIMPLIFY IT!


3q = 18


DIVIDE 3 to BOTH SIDES

3q/3 = 18/3

CANCEL out: 3/3 because it gives you 1

KEEP: 18/3 because it give you the q-value.


NEW EQUATION: q = 18/3


SIMPLIFY IT!


q = 6


Therefore, your answer is: q = 6


Good luck on your assignment & enjoy your day!
