4n + 3 = 67

Question

Answer 

Answer 1

4n + 3 = 67              subtract 3 from both sides

4n = 64                    divide  both sides by 4

n = 16

 

{16}

Answer 2

4n + 3 = 67

4n = 64         [subtract 3 from both sides]

n - 16              [divide both sides by 3]

 

43=5b-7

50 = 5b             [add 7 to both sides]

10 = b              [divide both sides by 10]

b = 10             [equals may be written either way]
