Question

15х +6y = 21
7х + бу = -3
What is the solution for each of these​

Answer 1

15x +6y = 21. is equal to 0

7x +6y = -3. is equal to 0

Explanation:

15x +6y = 2 is equal to 0 because when we move the constant to the left and divide both sides of the equation by 3 we get:

5x + 2y - 7 = 0

Same with 7x +6y = -3, when we move the constant to the left and sum the two opposites equal to 0 it give us:

7x + 6y + 3 = 0
