Y + 7 = 3x.....y = 3x - 7
6x - 2y = 12
6x - 2(3x - 7) = 12
6x - 6x + 14 = 12
14 = 12 (incorrect)
when ur variables cancel out and u r left with an incorrect statement, this means there is no solution because ur lines are parallel
so ur answer is : no solution

a=(729)^1/3
a=9
Answer:
2
Step-by-step explanation:
I dont know for sure though...
Since there is nothing on the left side of the equation besides the absolute value, you have to take 6m out of the absolute value and create 2 separate equations. These 2 equation will be 6m = 42 and 6m = -42.
You solve the equations normally:
6m = 42 6m = -42 (inverse to get m by itself, do on both sides)
/6 /6 /6 /6
m = 7 m = -7
The answer is a solution set:
[7, -7]
