Examine the system of equations.

x + 3y = 7,

2x + 4y = 9

Which variable would be the most efficient to solve for?
x in the first equation
y in the first equation
x in the second equation
y in the second equation

X, All you have to do is subtract 3y

Step-by-step explanation:

Your answer would be A. x in the first equation.

Step-by-step explanation:

use formula for the circle a=3.14

step-by-step explanation:

∠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.
