<h2>Answer:</h2><h2>The height of the triangle = 4cm</h2>

Step-by-step explanation:

Given, area of the triangle = 10 $cm^{2}$

Let the height of the triangle be h cm

Given, the base b is 3 cm less than twice its height.

b = 2h - 3 ... (1)

By formula, area of the triangle = $\frac{1}{2}$ bh .. (2)

substitute (1)in (2), we get

Area = $\frac{1}{2}$ (2h-3) h

10 = $\frac{1}{2}$ (2h-3) h

20 = $2h^{2} - 3h$

$2h^{2} - 3h$ - 20 = 0

solving the equation, we get x = 4, -2.5

The height of the triangle = 4cm

From second equation y = 8 - x so

7x + 2(8 - x) = -14
5x = -14 - 16 = -30
x = -6

and y = 8 - -6 = 14

Answer x=-6,y=14
