5x-6y+87z=6x+96y-867z

Mathematics
1 answer:
sasho [114]4 years ago

Answer:

The given equation cannot be solve but can be simplified.

Step-by-step explanation:

Given equation:  5x-6y+87z = 6x+96y-867z

We can only simplify the equation, but we cannot solve because there are three unknown variables and only one equation.

To successfully solve, we requires minimum of three equations.

lets simplify it:

  • first place the similar variables at one place:

                    5x - 6x -6y - 96y +87z +867z =0

  • Now perform the respective operation to the constants:

                              -x-102y+ 953z =0

                       ⇒   x +102y + 953z =0

Which is the required simplification.

The quotient of a number and -7,<br> decreased by 2, is 10. Find the<br> number.
garik1379 [7]

Answer:

-84

Step-by-step explanation:

Let the number be x. Then we have,

\frac{x}{-7} (the quotient of a number and -7)

\frac{x}{-7}-2 (decreased by 2)

\frac{x}{-7}-2=10 (is 10)

Now we can solve for x,:

\frac{x}{-7}-2=10

\frac{x}{-7}=12

x=-84

So, the original number is -84
