SOLUTION: Andy reads 56 more pages of his book on Monday than on Tuesday. He reads 125 pages on Monday. How many pages in all does he read on Monday and Tuesday?
M = 125
Substitute 125 for M in this equation
M = T + 56
which gives:
128 = T + 56
Subtract 56 from both sides of the equation:
128 = T + 56
-56 -56
-------------
72 = T + 0
72 = T
How many pages in all does he read on Monday and Tuesday?
