Directions: Write an equation and solve. Label the answer.

1. Two more than five times a number is 57.

x = a number

Solution:

• Write an equation to match the problem: 2 + 5x = 57


• Solve. Subtract 2 from both sides. 5x = 55


• Solve for x by dividing both sides by 5.^55 푥푥=^555
  Answer: x =11

2. Hank scored 32 points in a basketball game. This is 4 more than twice as many points as
   he scored the week before. How many points did Hank score the week before?

x = Hank’s points in previous game

Solution:

• Write an equation to match the problem: 32 = 4 + 2x (32 is 4 more than twice the points in previous games)


• Solve. Subtract 4 from both sides. 28 = 2x


• Solve for x by dividing both sides by 2. 282 =2푥푥 2

Answer: x = 14
