Question

Is (1,8) a solution to this system of equations? 19x+3y=2 3x+y=11

Answer 1

Answer:

No (1,8) is not a solution to 19x+3y=2.

However, (1,8) is a solution to 3x+y=11.

Step-by-step explanation:

(1,8)

The one represents the x shown in each equation, the eight represents the y.

Substitute the one in for the x and the eight in for the y.

19x+3y=2

19(1)+3(8)

3x+y=11

3(1)+(8)

Next, solve the equation.

19(1)+3(8) = 43

3(1)+(8) = 11

As you can see, 43 does not equal 2.

But, 11 does equal 11.
