3 (4x-5) = 45 show working

4^3x2^3=

3 x 4x = 12x

3 x - 5 = - 15 12x - 15 = 45

+15 + 15

12x = 60

divide by 12

x = 5

3 (4x - 5) = 45

first use the distributive property to clear the parenthesis

3*4x + 3*-5 = 45

12x - 15 = 45

add 15 to both sides

12x - 15 + 15 = 45 + 15

12x = 60

to clear the multiplication by 12, divide by sides by 12

12x/12 = 60/12

x = 5
