Answer:
no solution
Step-by-step explanation:
12x - 42 - 3 = 12x - 21
12x - 45 = 12x - 21
-45 ≠ -21
Answer:
No solution
Step-by-step explanation:
6(2x - 7) - 3 = 12x - 21
First, you have to use the distributive property on the left side.
12x - 42 - 3 = 12x - 21
You will have to add like terms on the left side.
12x - 45 = 12x - 21
Now you can subtract 12x (from either side) from both sides.
12x - 45 - 12x = 12x - 21 - 12x
-45 = -21
-45 is not equal to -21, therefore, there is no solution, or the euqation is not true.
