Answer:
x = -1, y = 1
Step-by-step explanation:
Given that:

Isolate x for 4x + 11y = 7 which ⇒ 
Substitute
into the equation: which is:

Drop Down to:

Isolate y for 7-8y = -1: y = 1
Thus, 
Substitute y = 1
Hence,

Solution ⇒ x = -1 and y = 1

x² + 9x + 3
x = -2
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em>: (-2)² + 9(-2) + 3
- Exponents: 4 + 9(-2) + 3
- Multiply: 4 - 18 + 3
- Subtract: -14 + 3
- Add: -11
Área of rectangle= 18 x 14 = 252
Area or triangle=
30-18= 12
12 is the base of the triangle
14 is the height of the triangle
Area of a Triangle= 1/2bh
1/2(12)(14)=84
Área of Triangle= 84
252+84= 336
Answer= 336
