Answer:
None
Step-by-step explanation:
Let's attempt to solve the equation, and see what happens:
-2(3x-1) = -6x -1
-6x +2 = -6x - 1 (expanding the brackets).
2 = -1 (cancelling out the -6x term from each side).
So, since 2 = -1 is not true, this means there are no solutions to this equation.
Answer:
(-6, 9) is the solution set for given system.
Step-by-step explanation:
Given that:
3x-y=-27 ----------- eq1
4x+2y=-6 --------- eq2
Solving by combining the equations:
Dividing eq2 by 2 we get:
2x + y = -3 ------- eq3
Now add eq1 and eq3, we get:
5x = -30 (y from both equations will be cancelled out)
Dividing both sides by 5:
x = -6
Now putting value of x back in eq3:
2(-6) + y = -3
-12 + y = -3
Adding 12 on both sides:
y = -3 + 12
y = 9
So the solution set for given system is (-6, 9)

Right away, you can tell that the number is greater that one if the exponent is positive. For example, 1.23 x 10 to the power of 2 would be 123, which is greater than 1. If the exponent is negative, the answer will most likely be less than 1. For example, 1.23 to the power or -2 would be .0123.
Hope this helps!
