Solve for x in the expression 3(x−5)=12 .

x=9

Step-by-step explanation:

3(x-5)=12 is equal to (3×x)-(3*5)=12

so:

3x-15=12

we want to get x by itself. so we are gonna get our variable and our constant on opposite sides.

so we will read 3x-15 as 3x and negative 15. how do we get to 0 from negative 15? we add 15 because the opposite of - is +.

so:

3x - 15= 12

+15. +15

3x. = 27

since we still want x alpne we are going to have divide the whole equation

3x/3=x

27/3=9

therefore x=9
