solve the system of equations using elimination/combinations
- 2x - y = - 4
x = 2y = 5

Step-by-step explanation:

Okay so solve this this is how you do it

and

To cancel out the X we have to make x into 2 x

we can cancel out -2x and 2x now leaving us with

add them both and solve for y

Now just substitute 2 for y

Or

In both the equations your answer will be the same

Hope this helps :)

If you have an doubt or need further help just reply :)

a negative exponent is translated as follows:

so, we have

126 maybe. sorry
