What is the result of adding these two equations? 5x-9y=1 -7x+2y=-5

Solution = -2x-7y=-4

Step-by-step explanation:

Add the x-component to the x-component, add the y-component to the y-component, add the number to the number.

It looks like this

5x + (-7x) = -2x

9y + (-2y) = -7y

1 + (-5) = -4

Then, put the solutions in the places where you see them in the equation, x goes first, y comes second, then this equals the number value.

-2x - 7y = -4

his chances of getting a coin of higher value is 4/19

step-by-step explanation:

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
