tensa zangetsu [6.8K]

Answer:

7/20. or .035 as a decimal

Step-by-step explanation:

the 2 subtractions would cancel out so it would be -1/4+3/5. then you would times both equations by the opposite bottom number which would turn into -5/20+12/20 which is just -5+12 all under 20 which then when you add -5 and 12 it would be 7. so its 7/20
