Answer:
0
Step-by-step explanation:
The determinant of this matrix is zero (0).
In this question, you have to isolate <em>x</em>.
First, use the distributive property.
Now that you have distributed, subtract the constants.
Answer:
0x+2y=22
Step-by-step explanation:
Set them equal to each other, (5x+4y=25)-(5x+2y=3). Distribute the negative into the right equation, (5x+4y=25)(-5x-2y=-3). Then combine like terms to get your answer.
