Solving Add and Sub Equations

Which procedure could be used to find the value for x that makes the statement true?
 
x + 22 = 64

• Multiply both sides of the equation by 22

• Divide both sides of the equation by 22

• Add 22 to both sides of the equation

• Subtract 22 from both sides of the equation

x - 5.5 = 13.53

• x = 8.03

• x = - 8.03

• x = - 19.03

• x = 19.03

5 + a = 37

• a = 37/5

• a = 42

• a = 185

• a = 32

y - 71 = 211

• 280

• 140

• 282

• 380

What should be done to both sides to isolate the variable? ___

6 + b = 1.3

• +1.3

• -1.3

• +6

• -6

The goal when solving an algebraic equation is to isolate the variable.

• True

• False

5(-2x + 10) = 170

• x= 12

• x= -12

• x= -22

• x= 22

-7(-4x + 9) = -315

• x= 13.5

• x= -13.5

• x= 9

• x= -9

7(2x + 9) = -7

• x= -5

• x= 5

• x= -4

• x= 4

2x - 3 + 4x = 27

• 12

• 4

• 5

• 15
