What if i have this equation 12-(4-5x)+4=2

Step-by-step explanation:

12-(4-5x)+4=2

12 - 4 + 5x +4 = 2

           5x  = 2 -12 +4 -4

5x = -10

x =  -10/5

x = -2

x = -2

Step-by-step explanation:

So first we have to Distribute;

12 -(4 - 5x) + 4 = 2

12 - 4 + 5x + 4 = 2

Next, collect like terms;

12 + 5x = 2

Subtract 12 from both sides;

5x = -10

Divide both sides by 5

x = -2

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
