Answer: x=4 and y=1

Step-by-step explanation:

From the first equation, we get y = 9 - 2x. Substitute this into the second equation we get

3x - 4(9 - 2x) = 8

3x - 36 + 8x = 8

11x = 44

x = 4

y = 9 - 2(4)

y = 1

Hope this helps

Solve :1/1-x^a-b +1/1-x^b-a​
Stolb23 [73]

The answer  to the above eqaution is 1

Step-by-step explanation:

Proceeding step by step

Step 1= 1/(1-xᵃ⁻ᵇ)+ 1/(1-xᵇ⁻ᵃ)

on rearranging the equation (b-a) as -(a-b) and substituting the value

Step 2= 1/(1-x ᵃ⁻ᵇ) + 1/(1-x -⁽ᵃ⁻ᵇ⁾ )

Using the indices corrolary that 1/1- x ⁻ᵃ= -xᵃ/ (1- x ᵃ) and subsituting the value of the expression in the step mentioned below

Step 3=1/(1+x ᵃ⁻ᵇ) - (x ᵃ⁻ᵇ)/(1-x ᵃ⁻ᵇ)

Since the denominators are the same the two fractions can be added with common denominator being 1+x ᵃ⁻ᵇ

On adding the above mentioned step 3 we get

Step 4=(1- x ᵃ⁻ᵇ) / (1- x ᵃ⁻ᵇ)

          =1

Thus the value of equation =1
