Question

1: 12 x + 8 (2 - 3x) = 100 - 5(25x+3)

2: m (15 - 8) + 16m = 200 + 14 (2m + 9)

Answer 1

Respuesta:

12x+8(2-3x)=100-5(25x+3)

12x+16-24x=100-125x-15

12x-24x+125x= 100-15-16

113x= 69

x= 69/113

m(15-8)+16m=200+14(2m+9)

15m-8m+16m= 200+28m+125

15m-8m+16m-28m=200+125

-5m= 325

m= 325:(-5)

m= -67
