Answer:
whoever kait is they are special to you so hold on to them
Step-by-step explanation:
If you would like to solve the system of equations 3y + 2z = 12 and y - z = 9, you can do this using the following steps:
<span>3y + 2z = 12
y - z = 9 ... y = 9 + z
</span>___________
<span>3y + 2z = 12
</span>3 * (9 + z) + 2z = 12
27 + 3z + 2z = 12
5z = 12 - 27
5z = -15
z = -15/5
z = -3
<span>y = 9 + z = 9 - 3 = 6
</span>
The correct result would be <span>c. y = 6, z = –3.</span>
Answer:
51
Step-by-step explanation:
Kx+9=7
Kx=-2 (subtract 9 from both sides)
X=-2/k (divide k from both sides.
