Choose the best choice that describes a possible first step in solving the system of equations. \large 2x-7y=-14 \large -2x+y=-10 a Substitute -10 for x in the first equation. b Solve for y in the second equation. c Substitute -14 for y in the second equation. d Solve for -2x+y in the second equation.

system of linear equation

step-by-step explanation:

as given in the data

a= 20 , b= -12

let us suppose that it is a straight line equation

now we know the formula for the system of linear equation

b= ma + c )

here m is slope of a straight line which is equal to formula

m=   (ii)

and here c is a constant

now putting the value of a and b in equation (ii)

m=

m=

putting the value of a,b and m in equation (i) gives us

-12 = + c

-12=-12 + c

adding 12 to both sides

-12 +12 = -12 +12 +c

0 =c

or c=0

as the value of the constant is zero which gives us that it is a linear equation and this order pair satisfies the system of linear equations.

try quizlet : ) hope this

y∈r, 8> y≥0

hope i !

p.s the first bit only matters if you know what that means.
