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.
