b * 7 = 133 . ______________________________________________ What is: "a" ? ______________________________________________ 133 / 7 = 19 = b ;
a + 5 = b = 19 ;
a + 5 = 19 ;
Subtract "5" from each side of the equation; to isolate "a" on one side of the equation; and to solve for "a" ; _______________________________________________ a + 5 − 5 = 19 − 5 ;
to get: ________________________________________________ a = 14 . ________________________________________________ Let us check our answer:
Start with "14" ;
Add "5" : "14 + 5 = 19 " . ______________________ then multiply by "7" : "19 * 7" __________________________ and the result is: 133 ? __________________________ 19 * 7 = ? 133 ? Yes! __________________________
