Question

Is (1, 1) a solution to this system of equations? 4x + 6y - 10 x + 13y = 11 yes no Submit

Answer 1

Step-by-step explanation:

Given 4x + 6y - 10x + 13y = 11

If (1, 1) is a solution, then substituting x = 1 and y = 1 into the left hand side of the equation gives 11.

Doing this, we have:

4(1) + 6(1) - 10(1) + 13(1)

= 4 + 6 - 10 + 13

= 13
