Answer:
x = 1
Step-by-step explanation:
2x + 8 = 4x + 6
<em>subtract 6 from both sides of the equation</em>
2x + 8 - 6 = 4x + 6 - 6
2x + 2 = 4x
<em>subtract 2x from both sides of the equation</em>
2x - 2x + 2 = 4x - 2x
2 = 4x - 2x
2 = 2x
<em>divide both sides of the equation by 2</em>
2/2 = 2x/2
1 = x

Proving the converse of the Pythagorean Theorem means proving that if the <u>sum</u> of the squares of the lengths of the <u>shorter</u> sides of a triangle equals the square of the length of the <u>longest</u> side, then the triangle is a right angle triangle.
Here's the equation:
(short side)² + (short side)² = (long side)²
Answer:
1) x=3, y=-3
Step-by-step explanation:
10x + 7y = 9 —— (1)
-4x -7y = 9 —— (2)
(1) + (2)
6x = 18
x = 18/6
x = 3
put x=3 in (1)
10(3) + 7y = 9
30 + 7y = 9
7y = 9 - 30
7y = -21
y = -21/7
y = -3
