"a number" refers to a variable.

Can someone write an equation out of X= -4 Y= -8 Z= 3
ICE Princess25 [194]

Answer:

2y + 4z = x

Step-by-step explanation:

Given

x = -4

y = -8

z = 3

Required

Write an equation that which is true for the above parameters

<em>This question will be answered using trial by error method and the solution is not limited to one equation.</em>

<em></em>

One equation that matches the values above is:.

2y + 4z = x

To check:

Substitute the values of x, y and z in the above equation.

2y + 4z = x

2 * -8 + 4 * 3 = -4

-16 + 12 = -4

-4 = -4

Hence,

Because both sides of the equation are one and the same (-4), 2y + 4z = x is true for the above values of x, y and z.
