Answer 2

Answer:

The value of x is 3 and y is - 2.

Step-by-step explanation:

Given Equations:

141x+103y=217 ----------------- Equation (1)

103x+141y=27 --------------------- Equation (2)

Adding Equation 1 and Equation 2:

244x + 244y = 244

244(x + y) = 244 (Taking 244 common)

x + y = 244 / 244

x + y = 1 ------------------- Equation 3

Subtracting Equation 1 and Equation 2:

38x - 38y = 190

38(x - y) = 190

x - y = 190 / 38

x - y = 5 ---------------- Equation 4

Solving Equation 3 and Equation 4:

x + y = 1 ---------- Equation 3

x - y = 5 ---------- Equation 4

2x = 6

x = 6 / 2 = 3

Putting value of x in Equation 3:

3 + y = 1

y = 1 - 3 = -2

Therefore, the value of x is 3 and y is - 2.
