Question

como se solucionan estas ecuaciones
-2x+(3*5)+18=47
-2*(2x-3)=6+x
-2x+9-(3x+7)=3

Answer 1

-2x+(3*5)+18=47
-2x + 15 + 18 = 47
-2x + 33 = 47
33-47 = 2x
-14 = 2x
-7 = x


-2*(2x-3)=6+x
-4x+6= 6+x
6-6 = 4x + x
0 = 5x
0 = x


-2x+9-(3x+7)=3
-2x + 9 -3x - 7 = 3
-5x +2 = 3
2-3 = 5x
-1 = 5x
-1/5 = x
