Question

Solve − 2 x − 10 y = 10

Answer 1

x=-10 and y=1

Explanation:

-2(-10)=20

-10(1)=-10

20-10=10

Answer 2

Step 1: isolate the "x" by bring everything else to the other side

`-2x-10y=10\\-2x= 10 +10y\\x= -5 -5y`

Step 2: The equation found above is the equation x is equal to so you plug it into all the x's the original equation to find y

`-2 (-5 - 5y) -10y = 10`

`10 + 10y -10y = 10\\10y - 10y = 0\\0y = 0\\y = 0`

Step 3: Plug in your newly found y (0) into the original equation to find the x

`-2x- 10(0) = 10\\-2x - 0 = 10\\-2x =10\\x = -5`

Hope this helped! Let me know if there is anything I need to clarify or explain more in depth!
