\huge\red{Answer:--}

\large\mathbb{a\:+\:b\:=\:4....... 1.}

\large\mathbb{a\:-\:b\:=\:2....... 2.}

----------------------------- Adding

2a = 6

a = 3

putting this value in eq. 1.

\mathbb{3\:+\:b\:=\:4}

b = 1

Now you have two points

A = (3,0)

B = (0,1)

Using two point form :--

(y - y0) = \large\frac{y2-y1}{x2-x1} × (x - x0)

(y - 3) = \large\frac{1-0}{0-3} × (x - 0)

(y - 3) = \large\frac{1}{-3} × x

(y - 3) = \large\frac{-1}{3} x

3(y-3) = -x

3y - 9 = -x

x + 3y - 9 = 0

This is the required equation.
