Answer:

(2, 3)

Step-by-step explanation:

3x + 4y = 18

-1 (-2x + 4y) = (8)-1

2x - 4y = -8

<em>Elimination</em>: Side work:

3x + 4y = 18 3x + 2x = 5x

<u> 2x - 4y = -8</u> 4y - 4y = nothing

5x = 10 18 - 8 = 10

x = 2 Divide by 5 on both sides

Substitute back in to one of the equations

x = 2

3x + 4y = 18

3(2) + 4y = 18

6 + 4y = 18

4y = 18 - 6 Subtract 6 on both sides

4y = 12 Divide by 4 on both sides

y = 3

6 acts as the base. 15 acts as the height, because it extends from the base to meet vertex opposite the base at a 90° angle.

General formula for triangle area
a = 1/2 × b × h

plug in the numbers
a = 1/2 × 6 × 15
a = 90/2
a = 45

The area of the triangle is 45 units²
