Question

What is the value of z in the equation 4(2z + 3) = 12?

Answer 1

First u have to expand the brackets...
4 x 2z = 8z
4 x 3 = 12
8z + 12 = 12
Then you have to get numbers on one side, and letter on the other...
8z -12 = 12-12
8z = 0
then u have to divide 8z by 8 to find 1z or just z.
z = (0/8) = 0
z=0
Hope this helps :)

Answer 2

4(2z+3)=12
(4)(2z)+(4)(3)=12(Distribute)
8z+12=12
Step 2: Subtract 12 from both sides
8z+12−12=12−12
8z=0
Step 3: Divide both sides by 8
8z/8=0/8
z=0
