In an equation or inequality, you want to get the variable...

• on one side
• to disappear
• by itself

To Solve the Equation Below, you'd
x - 62 = 123

• add 62 to each side
• subtract 62 from each side
• multiply each side by 62
• Add 123 to each side

x+ 3=10

• 3

• 10

• 13

• 7

Evaluate: -35 + y= 70

• 35

• -35

• 105

• -105

• k = 190

• k = -9

• k = 29

• k = 10/19

• x = 7

• x = 35

• x = 294

• x = 1.5

• j = -7/10

• j = -34

• j = 280

• j = 6

• y = -35

• y = 2

• y = -12

• y = 5/7
