9x -8 equals 55 what is x?

Answer 1

9x - 8 = 55

Add '8' to both sides

9x - 8 + 8 = 55 + 8

Hence

9x = 63

Divide both sides by '9'

9x/9 = 63/9

x = 7

NB Remember in mathematics , the four functions add(+), subtract)-), multiply(x) and divide (/) , whatever you do to one side of the 'equals(=) , you must do to the other , in order to preserve equality. Its like a balance scales, you MUST keep it in balance.
