9x - 10 = 5x + 14 solve the equation and check it

Step-by-step explanation:

9x-10=5x+14

9x-5x=14+10

4×=24 /:4

x=6

How do we check that?

9x-10=5x+14

(9×6)-10=(5×6)+14

54-10=30+14

44=44

L=R

x =-.20752

step-by-step explanation:

4^(x+2)=12

4^(x+2)=12

take the log base 4 on each side

log 4 (4^(x+2) = log 4(12)

we know log b(a^y) = y log b (a)

(x+2) log 4(4) = log 4 (12)

x+2 = log 4 (12)

we know   logb c = loga c/loga b

we want to convert to base 10   so a = 10

by default, we do not write the 10   c = 4   and b = 10

log4 10 = log 12/log 4

log4 10 = log 12/ log 4

x+2 = log 12/ log 4

subtract 2 from each side

x +2 -2 = log 12/ log 4 -2

x = 1.79248125 -2

x =-.20752
