Given that 5x-2y = 9 and 3x-2y =7 , find x.

a) -2
b) -1
c) 1
d) 4

C

Step-by-step explanation:

Given the 2 equations

5x - 2y = 9 → (1)

3x - 2y = 7 → )2)

Multiplying (2) by - 1 and adding to (1) eliminates the term in y

- 3x + 2y = - 7 → (3)

Add (1) and (3) term by term

(5x - 3x) + (- 2y + 2y) = (9 - 7), that is

2x = 2 ( divide both sides by 2 )

x = 1 → C

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

step-by-step explanation:

given   that triangle lno is congruent to triangle lnm.

we have to fill up the blanks in the given question.

according to above order of congruency   kept in mind we can say that

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

ln ≅ ln due to common in both.

hence, by sas congruency,

the side angle side rule   states that if two sides and the included angle of one triangle are congruent to another triangle, then these two triangles are congruent.
