Solve a system of equations using any method
y = 2x - 5
y = -2x - 9

x= -1

Step-by-step explanation:

2x-5=y

-2x - 9 = y

so this means that they equal each other

2x-5=-2x-9

Add 5 to both sides

2x=-2x-4

Add 2x to both sides

4x=-4

divide 4 on both sides

x=-1

assuming you mean addition: addition and subtraction are reverse operations.

step-by-step explanation:

your answer would be 10x - 1
