Answer:
x₁=(-4-8t)
y₁= 4+5t
Step-by-step explanation:
70x + 112y = 168---------------(1)
First we have to find the gcd of 70 and 112.
112 = 70×1 + 42
70 = 42×1 +28
42 = 28×1 + 14
28 =14×2 + 0
∴gcd (70, 112) = 14
Therefore, equation (1) has a solution.
Dividing Equation(1) by 14 we get
5x + 8y = 12
We see that x = -4, y =4 satisfy the above equation. Its general solution is given
x₁=x₀-=(-4-8t)= -4(1+4t)
y₁=y₀-= 4+5t
