Question

Solve using the elimination method x + 5y = 26 - X+ 7y = 22​

Answer 1

Answer:

x = 6, y = 4

Step-by-step explanation:

x + 5y = 26

- x + 7y = 22

_________

0 + 12y = 48

12y = 48

y = 48 / 12

y = 4

Substitute y = 4 in eq. x + 5y = 26,

x + 5 ( 4 ) = 26

x + 20 = 26

x = 26 - 20

x = 6

Answer 2

Answer:

$x=6\\y=4$

Step-by-step explanation:

Elimination method:

$x+5y=26$

$-x+7y=22$

Add these equations to eliminate x:

$12y=48$

Then solve $12y=48$ for y:

$12y=48$

$y=48/12$

$y=4$

Write down an original equation:

$x+5y=26$

Substitute 4 for y in $x+5y=26$:

$x+5(4)=26$

$x+20=26$

$x=26-20$

$x=6$

{ $x=6$ and $y=4$ }    ⇒ $(6,4)$

hope this helps...
