Question

3×=36
×+3=99
5×+12=27
3×-2=4×-4
5+2×=5×-1
​

Answer 1

Respuesta:

1)    3x = 36

      x = 36 - 3

      x = 33

2)   x + 3 = 99

     x = 99 - 3

     x = 96

3)  5x + 12 = 27

    5x = 27 - 12

    5x = 15

    x =   $\frac{15}{5\\}$

    x = 3

   

4)   3x - 2 = 4x - 4

     3x - 4x = -4 + 2

     -x = -2

      x = 2

5)   5 + 2x = 5x - 1

     2x - 5x = -1 - 5

    -3x = -6

     x = 2
