Question

x+(-4)= -1
x-25=72
x+67=125
x+3=-78
-x+3=-125
x-12=32
necesito saber su procedimiento

Answer 1

x+(-4)=-1 -> x-4-1=0 -> x-5=0 -> x=5
x-25=72.... x=72+25... x=97
x+67=125....x=125-67....x=58
x+3=-78... x= -78-3 ... x=-81
-x+3=-125... -x= -125-3... x=-128/-1 ... x=128
x-12=32... x-12= 32.... x=32+12...x=44
