Determine the equivalent system for the given system of equations: 2x + 3y = 7
4x − 2y = 4

A:
2x + 3y = 7
8x − 4y = 4
B:
2x + 3y = 7
6x + y = 11
C:
−2x − 3y = 7
4x − 2y = 4
D:
2x + 3y = 7
6x + y = 4

answer: it is 8

step-by-step explanation:

you know why its 8

47

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
