Question

Determine whether the point (1, 7) is a solution of the system

2x + 6y = 50

10x + 0y = 10

by substituting the point into each equation.

Answer 1

Are you sure it's 0y?

Answer 2

yes

Answer 3

If that's tru then they really gave you x and you can plug it right in the top to get y:
\[10x=10\]
\[x=1\]

Answer 4

It's not a solution

Answer 5

how u get that

Answer 6

I graphed the first one, then I traced it to x = 1.

Answer 7

You don't get 7 for y, you get 8

Answer 8

can u like show the work

Answer 9

You don't have a graphing calculator?

Answer 10

I can do it here.....

Answer 11

I agree with Hero. When you plug 1 into the first equation and subtract the x value the remainder is 48 which when divided by 6 is 8.
\[(2)(1)+6(y)=50\]
\[6y=48\]
\[y=8\]

Answer 12

yeah....there ya go
