3+x=5

• 1

• 2

• 3

• 0

75 + n = 100

• n = 25

• n = 30

• n= 15

• n = 175

What step can be taken to get the x by itself on one side in the equation x + 18 = 50 ?

• Multiply both sides of the equation by 18

• Divide both sides of the equation by 18

• Add 18 to both sides of the equation

• Subtract 18 from both sides of the equation.

57 + c = 93

• c = 37

• c = 97

• c = 36

• c = 27

x + 19 = 46

• x = 18

• x = 23

• x = 27

• x = 65

2.8 + z = 3.5

• z = 0.7

• z = 1.7

• z = 3.5

• z = 6.3

x + 4 = 16

• x = 12

• x = 20

• x = 13

• x = 25

m - 9 = 81

• m = 89

• m = 78
