... reduces to 17. Likewise , 5 a + 3b - 2 c then becomes equal to 5 , while 7 a - 9 b - 5 c becomes equal to -26 . The sum of the three is , therefore , 17 + 5-26 , which reduces to -4 . But , the answer obtained above , namely 15 a - 2 b ...

... reduces to 2x = x + 1 + 5 , 2x = x + 6 . Likewise , the second step ( which was to subtract x from both sides of the equation 2 x = x + 6 ) practically amounts to getting rid of the x on the right side by 71 SIMPLE EQUATIONS.

... reduces to -x + 2x = 6 , x = = 6 . Whenever we get rid of a term on either side of an equation in this way we are said to transpose it . Much time can be saved in making use of this idea , since we can often trans- pose a number of ...
