Answer:
4w-v
Step-by-step explanation:
Let the number be<em> </em><em>w.</em>
Multiplying by 4:
Subtracting v,
Answer:
x = 4
y = -1
z = 3
Step-by-step explanation:
Let 1st number = x
Let 2nd number = y
Let 3rd number = z
x+y+z=6
x+y=z
x=z+1
(Apply Simultaneous Equations)
Hence:
z+z=6
2z=6
z=6/2
z=3
Now:
x+y=3
x=3+1
x=4
Now:
4+y=3
y=3-4
y=-1
167, 15, -65, -110, -197, -200
Answer:
I did this exact same question on USATestPrep and here's what I answered that I got correct:
