SDAY:

ve the equation:

5x - 2 (x + 7) = - 5

5x - 2 (x + 7) = - 5

mutiply the bracket by - 2

(-2) (x) = - 2x

(-2) (7) = - 14

5x-2x-14=-5

3x-14 = - 5

move - 14 to the other side, sign changes from - 14 to + 14

3x-14+14 = - 5+14

3x = 9

divide by 3 for both sides

3x/3 = 9/3

x = 3

Answer: x = 3
