4x + 5y - 3 = 0
4x + 5y = 3
3x - 7y - 13 = 0
3x - 7y = 13
4x + 5y = 3......multiply by 3
3x - 7y = 13....multiply by -4
---------------
12x + 15y = 9 (result of multiplying by 3)
-12x + 28y = - 52 (result of multiplying by 4)
---------------add
43y = -43
y = -43/43
y = -1
3x - 7y = 13
3x - 7(-1) = 13
3x + 7 = 13
3x = 13 - 7
3x = 6
x = 6/3
x = 2
so ur solution is : (2,-1) <==
angles and sides opposite one another on a parallelogram are congruent, we can say this is a parallelogram because there are congruent.
What in mathematics is a parallelogram?
- A quadrilateral with the opposing sides parallel is called a parallelogram (and therefore opposite angles equal).
- A parallelogram with all right angles is known as a rectangle, and a quadrilateral with equal sides is known as a rhombus.
Slope Formula: y2-y1/x2-x1
KL: 12-7/6-2 = 5/4
LM; 13-12/13-6 = 1/7
MN: 8-13/9-13 = 5/4
KN: 7-8/9-2 = 1/7
Since angles and sides opposite one another on a parallelogram are congruent, we can say this is a parallelogram because there are congruent.
