Answer:
5 and -3
Step-by-step explanation:
x+y =2
X-Y=-8
BY USING SIMULTANEOUS EQUATION
SUBTRACT SUCH THAT
2Y=10
SO Y = 5
X= -3
Answer:
y = 14x
Step-by-step explanation:
Use the direct variation equation, y = kx
Plug in 7 as y and 0.5 as x, and solve for k:
y = kx
7 = k(0.5)
14 = k
Plug this into the equation:
y = kx
y = 14x
So, the equation of variation is y = 14x
