Answer:
12z + 6
z = -1/2
Step-by-step explanation:
y(3z+2)
4(3z+2)-2
(12z + 8) -2
12z + 8 - 2
12z + 6
If going further,
12z = -6
z = -1/2

Answer:
Sam is 24; his mom is 48.
Step-by-step explanation:
We can let x and y represent Sam's age and his mom's age, respectively.
y = 2x . . . . . Mom is twice Sam's age
y -12 = x + 12 . . . . Mom's age 12 years ago is the same as Sam's age 12 years from now
__
Substituting for y in the second equation, we have ...
2x -12 = x + 12
x = 24 . . . . . . . . . add 12-x to both sides
y = 2(24) = 48
Sam is 24; his mom is 48.
Parallel lines are coplanar lines (lines that lie on the same plane) and they do not intersect.
It’s important to understand that they remain the same distance apart over their entire lengthy which means they never get closer together of farther away from each other.
