3x+7=19 what is the value of x

x = 4

Step-by-step explanation:

3x + 7 = 19

3x = 19 - 7

3x = 12 (divide both sides by 3 to get x)

3x/3 = 12/3

x = 4

PLS GIVE BRAINLIEST

4

Step-by-step explanation:

because subtract 4+7 which is 11 from 19 which is 7 and 4x3 equals 9 so X is 3

use the power rule  

( a b ) n = a n b n

to distribute the exponent.

apply the product rule to  

3 x 2 y 3 . ( 3 x 2 ) 2 ( y 3 ) 2

apply the product rule to  

3 x 2 . 3 2 ( x 2 ) 2 ( y 3 ) 2

raise  

3

to the power of  

2 . 9 ( x 2 ) 2 ( y 3 ) 2 multiply the exponents in   ( x 2 ) 2

.

apply the power rule and multiply exponents,  

( a m ) n = a m n . 9 x 2 ⋅ 2 ( y 3 ) 2

multiply  

2   by   2 . 9 x 4 ( y 3 ) 2

multiply the exponents in  

( y 3 ) 2 .

apply the power rule and multiply exponents,  

( a m ) n = a m n . 9 x 4 y 3

⋅

2

multiply  

3   by   2 . 9 x 4 y 6
