Answer:

(-18, 0)

Step-by-step explanation:

The x intercept has a y value of 0. So, to find the x intercept, plug in 0 as y into the equation, and solve for x:

y = 2/3x + 12

0 = 2/3x + 12

-12 = 2/3x

-18 = x

So, the x intercept is (-18, 0)

A-b = 43----(1)
a+b = 13----(2)

(1)+(2) 2a=56
then a=56/2= 28
so b=13-28= -15

so that the numbers are -15 and 28
