Question

Urgent please solve quickly please!

Answer 1

Answer: x = 0, y = 7

-x+y=7

add x to both sides

y=x+7

plug this in for y in the other equation

6x-(x+7)=-7​

simplify

6x-x-7=-7

simplify

5x-7=-7

add 7 to both sides

5x=0

divide both sides by 5

x=0

plug in to one of the equations to find y

-(0)+y=7

y=7

Therefore, x=0 and y=7.

Hope this helps!

Answer 2

Answer:

x = 0. y = 7. (0,7)

Step-by-step explanation:

-x+y=7

+x. +x

y = x +7

6x-y= -7

6x - (x + 7) = -7

6x - x - 7 = -7

5x -7 = -7

+ 7. +7

5x = 0

÷5. ÷5

x = 0

-x + y = 7

0 + y = 7

y = 7
