Solve an Equation

Solve for x: 7x = 21.

• x = 1

• x = 2

• x = 3

• x = 4

solving this equation y – 11 = 25?

• y = 14

• y = 15

• y = 36

• y = 37

solve for j. 27 - j = 8

• j = 13

• j = 15

• j = 17

• j = 19

Solve for k: 31 – 3k = 10.

• k = 5

• k = 7

• k = 9

• k = 11

What is the first step to solve this equation?
x + 8 = 10

• Subtract 8 from x 

• Subtract 8 from both sides 

• Subtract 8 from one side and add 8 to the other 

• Add 8 to both sides

x + 3 = 9

• 5

• 6

• 7

• 15
