Answer 1

Answer:

Step-by-step explanation:

Given,3(x-7)=24

=>3x-21=24

=>3x=24+21

=>3x=45

=>x=45/3

=>x=15

So,x=15

Answer 2

Solution :

Given linear equation in one variable

is 3( x - 7 ) = 24

Divide both sides by 3 , we get

=> [ 3( x - 7 )]/3 = 24/3

=> x - 7 = 8

Add 7 both sides of the equation,

we get

=> x - 7 + 7 = 8 + 7

=> x = 15

Therefore ,

x = 15
