When solving the following system of equations, which variable would be the easiest to solve for? 2x + 3y = 17
4x + y = 19

the y in the first equation
the x in the second equation
the y in the second equation
the x in the first equation

xy1

Step-by-step explanation:

Correct option is C)

Given two equations are 2x+y+4=0 and x=3y+7=0

let us consider 2 equations ax+by+c=0 and mx+ny+p=0

By cross multiplication method ,the equations obtained will be ,

b×p−n×c

x

=

c×m−a×p

y

=

a×n−b×m

1

Thus comparing it with given 2 equations we obtain:

7−12

x

=  

4−14

y

=  

6−1

hello :

70y^8 + 30y^6 = 2 ( 35 y^8 + 15y^6)

the lenght is : 35 y^8

the width is : 15y^6
