Which ordered pair is the solution to the system of equations? {2x−y=−5x+3y=22{2x−y=−5x+3y=22 (7, 19)(7, 19) (8, 21)(8, 21) (4, 9)(4, 9) (1, 7)

the answer is d on edge

step-by-step explanation:

option (a)

step-by-step explanation:

step 1:   take 2 number whose product equal to 25..

and sum of those two number are -10

step: 2 for example here if we take 5,5 are the number,,

5*5=25

and

5+5=10

but we need -10

so if we take   -5,-5

so -5*-5=25

and -5+(-5)=-10

s0

come the equation

replace -10x by these number

like -5x -5x+25

take common

x(x-5)-5(x-5)=0

(x-5)(x-5)=0
