Answer: z = -13
Step-by-step explanation:
6(10+z+3) =
60 + 6z + 18 =
6z = -60 -18
6z = - 78
z= - 78/6
z = -13
Answer: 13
Step-by-step explanation: 6 x 10, then do 6 x 1z, then 6 x 3.
You get 60 + 6z + 18.
Add your constants. (The numbers without variables)
You’re left with 78 + 6z.
Divide 6z/6, youre left with “z”.
Divide 78/6.
You’re left with z = 13
