Question

Resolver las ecuaciones de
1. 8-5×=8+2×
2. 5x-15+8× = 7×-5
3. 15 - 12 × + 24 = 8+ 10× -2

Answer 1

8-5×=8+2×

8-8=2x + 5x

0=7x

0=x

5x-15+8× = 7×-5  

5x+8x-7x=-5+15

     6x= 9

     x=9:6

    x=3/2

   x=1,5

15 - 12 × + 24 = 8+ 10× -2

15+24-8+2=10x+12x

       33=22x

     33:22=x

      x=3/2

     x=1,5
