Answer:

NO unless you know the value of m you are able to subtract a variable form a constant unless the constant is attached to the same variable. For example you can sub tract 7m-m and that would equal 6m but you can not subtract 7b-m because the variables are different. If you tink about it this way 7 can have the variable A attached to it to make it 7a and the variable m can be thought of as 1m. Therefor you can not have 7a-1m because the variables are different.

Solve the following equation <br><br> 1/x-1+1/x+2=3
disa [49]

Answer:

x = 1

Step-by-step explanation:

Solve for x over the real numbers:

-1 + 2 + 1/x + 1/x = 3

-1 + 2 + 1/x + 1/x = 1 + 2/x:

1 + 2/x = 3

Bring 1 + 2/x together using the common denominator x:

(x + 2)/x = 3

Multiply both sides by x:

x + 2 = 3 x

Subtract 3 x + 2 from both sides:

-2 x = -2

Divide both sides by -2:

Answer:  x = 1

If (x) = 3x - 5 and g(x) = x + 3, find (f - g)(x).
Temka [501]

Answer:

2x -8

Step-by-step explanation:

f (x) = 3x - 5

g(x) = x + 3,

(f - g)(x) = 3x - 5 - ( x+3)

Distribute the minus sign

            = 3x-5 -x-3

Combine like terms

           = 2x -8
