Question

Solve the equation.

42x – 5 = 64

Answer 1

Answer:

23/14

Step-by-step explanation:

42x - 5 = 64

Add 5 to both sides in order to isolate 42x

42x = 64 + 5

42x = 69

Divide 42 from both sides in order to isolate x

x = 69/42

The answer gives an uneven decimal so it'd be best to leave it as a simplified fraction. The simplified fraction is 23/14.

Answer 2

Answer:

x = 1.64

Step-by-step explanation:

42x – 5 = 64

add 5 to both sides

42x - 5 + 5 = 64 + 5

42x = 69

divide via by 42

x = 69/42

x = 1.64

Hope this helps!
