Answer: I believe it is 1/3 or -1.3. or 1.  Sorry if its not right.

Step-by-step explanation:

If it's correct you would make 2/5 into 4/10, 4/5 into 8/10. Then subtract 4/10-8/10=0/4 or -0.4. Then subtract (if its 1 then you would add 0.4+1=5 then turn 5 into 10/10 then subtract 10/10-9/10=1.) 0.4-9/10=1/3.

Hope 1 of these answers is right sorry if they aren't!!

Using the linear combination method what is the solution to the system of linear equations 7x - 2y = -20 and 9x + 4y = -6
Ghella [55]

x should equal -2 and y should equal -3 to solve this i multiplied the first equation by 2 then got rid of the 4y and -4y then i added the 14x to the 9 equaling 23x and added the -40 to the -6 which became 23x=-46 i solved this getting -s for x, then i plugged that into the equations to get y which was -3
