-2x+22=5x-20 i really need help with this!

x= 6

Step-by-step explanation:

-2x + 22 = 5x - 20

-2x + 22 - 22 = 5x - 20 - 22

-2x = 5x - 42

-2x - 5x = 5x -5x - 42

-7x = -42

-7x/-7 = -42/-7

x = 6

hope I'm right...

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
