Answer:
There is no solution.
Step-by-step explanation:
4y − 36 = −12x
3x + y = −9
Add 12x and 36 to both sides of the first equation.
12x + 4y = 36
3x + y = -9
Multiply both sides of the second equation by -4.
12x + 4y = 36
-12x - 4y = 36
Add the two equations.
0 = 72
Since 0 = 72 is a false statement, this system of equations has no solution.
Answer:
1-7i
Step-by-step explanation:
Multiply the parenthesis
-3-4i-3i-4i²
By Definition i²=-1
-3-4i-3i-4 x (-1)
Any expression multiplied by -1 equals its opposite
-3-4i-3i+4
Calculate the sum
1-4i-3i
Collect like terms
1-7i
