Hey there!

9(u + 2) = 63

9u + 18 = 63

SUBTRACT 18 to BOTH SIDES

9u + 18 - 18 = 63 - 18

CANCEL out: 18 - 18 because that gives you 1

KEEP: 63 - 18 because that helps solve for u

63 - 18 = 45

NEW EQUATION: 9u = 45

DIVIDE 9 to BOTH SIDES

9u/9 = 45/9

CANCEL out: 9/9 because that gives you 1

KEEP: 45/9 because that gives the result of u

u = 45/9

SIMPLIFY ABOVE AND YOU HAVE YOUR ANSWER

u = 5

Good luck on your assignment and enjoy your day!

Answer:

u = 5

Explanation:

9(u+2) = 63

Step 1: Distribute the 9

9u + 9(2) = 63

9u+18=63

Step 2: subtract 18 from both sides

9u = 45

Step 3: divide both sides by 9

u = 5
