Solve the system of equations. 6x – 3y = 3 –2x + 6y = 14 what number would you multiply the second equation by in order to eliminate the x-terms when adding to the first equation? what number would you multiply the first equation by in order to eliminate the y-terms when adding to the second equation?

Step-by-step explanation:

Multiplying the second equation by 3 results in -6x + 18y = 42, which, when added to the first equation, has only y as a variable.  The x terms are eliminated.

Mult. the first equation by 2 results in 12x - 6y = 6, which, when added to the second equation, results in a third equation in which x is the only variable; the y terms are eliminated.

option a, c,d are correct.

step-by-step explanation:

from the given figure, it is given that z is equidistant from the sides of the triangle rst, then from triangle tzb and triangle szb, we have

tz=sz(given)

bz=zb(common)

therefore, by rhs rule,δtzb ≅δszb

by cpctc, sz≅tz

also, from δctz and δasz,

tz=sz(given)

∠tcz=∠saz(90°)

by rhs rule, δctz ≅ δasz, therefore by cpctc, ∠ctz≅∠asz

also,from δasz and δzsb,

zs=sz(common)

∠zbs=∠saz=90°

by rhs rule, δasz ≅δzsb, therefore, by cpctc, ∠asz≅∠zsb

hence, option a, c,d are correct.
