Solve the following system of equations 2x + y = 3 x = 2y - 1

x = 1 , y = 1

Step-by-step explanation:

Solve the following system:

{2 x + y = 3 | (equation 1)

x = 2 y - 1 | (equation 2)

Express the system in standard form:

{2 x + y = 3 | (equation 1)

x - 2 y = -1 | (equation 2)

Subtract 1/2 × (equation 1) from equation 2:

{2 x + y = 3 | (equation 1)

0 x - (5 y)/2 = (-5)/2 | (equation 2)

Multiply equation 2 by -2/5:

{2 x + y = 3 | (equation 1)

0 x+y = 1 | (equation 2)

Subtract equation 2 from equation 1:

{2 x+0 y = 2 | (equation 1)

0 x+y = 1 | (equation 2)

Divide equation 1 by 2:

{x+0 y = 1 | (equation 1)

0 x+y = 1 | (equation 2)

Collect results:

 {x = 1 , y = 1

i think it's either c or d

step-by-step explanation: the entire question is extremely odd. 04 obviously refers to the interest rate. honestly i will say the answer is c. because the (2 x 12) part would mean it's compounded semiannually. i'll say choose 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.
