Answer:

x = 3

Step-by-step explanation:

log 10x + log 2 = log 60

Subtract log 2 from each side

log 10x + log 2 -log 2 = log 60 - log 2

log 10x = log 60 - log 2

We know that log a - log b = log (a/b)

log 10 x = log (60/2)

log 10x = log 30

We know log a = log b that a = b

10x = 30

Divide by 10

10x/10 = 30/10

x =3

Answer:

x=7

Step-by-step explanation:

Step 1: Subtract 4x from both sides.

x+30−4x=4x+9−4x

−3x+30=9

Step 2: Subtract 30 from both sides.

−3x+30−30=9−30

−3x=−21

Step 3: Divide both sides by -3.

−3x
