Question

Solve the following system of equations: 27/x + y - 15/x - y = -2 and 30/x + y-1/x - y = 3​

Answer 1

Answer:

(i) 27/x + y - 15/x - y = -2

→ Lets solve for x.

$\frac{27}{x}+y-\frac{15}{x}-y=2$

Step 1: Multiply both sides by x.

12= -2x

Step 2: Flip the equation.

-2x = 12

Step 3: Divide both sides by -2.

$\frac{-2x}{2} =\frac{12}{-2}$

x= -6

(ii) 30/x + y-1/x - y = 3​

→Let's solve for x.

$\frac{30}{x}+y-\frac{1}{x}-y$

Step 1:  Multiply both sides by x.

29 = 3x

Step 2: Flip the equation.

3x = 29

Step 3: Divide both sides by 3.

$\frac{3x}{3} =\frac{29}{3}$

x = 29/3
