Answer:

Step-by-step explanation:
Let's translate what you've written in words to an expression with mathematical symbols.

To solve this, you need to multiply both the numerator and denominator with the conjugate of the denominator.

Answer:
x = -3
Step-by-step explanation:
2x + y = -2
4x + y = -8
2x + y = - 2
y = -2x - 2
4x + y = - 8
y = -4x - 8
y = -2x - 2
y = -4x - 8
-2x - 2 = -4x - 8
4x - 2x = 2 - 8
2x = -6
2x/2 = -6/2
x = -3
To check just use da graph ;w;
The x is -3
-12.3f= -73.8
F multiplied by -12.3, you just put both thing down together and the equal sign and -73.8 the multiplication sign isn’t really necessary.
