Question 2(i)

Express the following linear equations in the form ax + by + c = 0 and indicate the values of a, b and c in each case :

2x + 3y = 9.35‾9.3\overline{5}

Answer

Given,

⇒ 2x + 3y = 9.35‾9.3\overline{5}

On re-arranging the equation, we have :

⇒ 2x + 3y - 9.35‾9.3\overline{5} = 0

⇒ (2)x + (3)y + (-9.35‾9.3\overline{5}) = 0

Comparing above equation with ax + by + c = 0, we get :

a = 2, b = 3 and c = -9.35‾9.3\overline{5}

Hence, linear equation : 2x + 3y - 9.35‾9.3\overline{5} = 0, a = 2, b = 3 and c = -9.35‾9.3\overline{5}.
