Question

Someone please solve this system of equation question?

Answer 1

Choose the equivalent system of linear equations that will produce the same solution as the one given
below.
4x – 2y = 6
2x + y = 5

A. –4x – 2y = 10
–4y = 4

B. –4x – 5y = –1
–7y = 5

C. 3x + 2y = 6
7x = 12

D. 4x + 2y = 10
8x = 16

Answer 5

4x-2y = 6
2x+y = 6
use substitution by using the first equation to make x as the function of y
\[x = (6 +2y)/4 \]
then, use substitution again by substituting the second equation by the first
\[2(6-2y)/4+y = 6\] <---- simplify this expression and you'll get 8y = 12
divide each side by 8 you'll get y=12/8

now we found out y, use y = 12/8 or 1.5 back into the x as a function of y:
x = (6+2(1.5))/4 = 2.25

Answer 6

for the first equation

Answer 7

x=2.25 and y=1.5
