Word problems leading to the algebraic equation:
Word problems in mathematics are words written with a mathematical approach and it requires the use of the student's understanding of various mathematical concepts to arrive at a probable solution to the word problems. Word problems are used in mathematics to solve our daily life challenges.
From the given information, given that:
- Let the first number be x
- One(second) number is 7 times the first number. Let that number be [tex]y = 7x[/tex]
- A third number is 100 more than the first number i.e [tex]z = 100 + x[/tex]
The sum of these three numbers is 910. i.e.
x+ y + z = 910
It implies that:
x + 7x + 100 + x 910
9x + 100 = 910
9x = 900 - 100
9x = 810
x = 90
y = 7(90) = 630
z = 100 + 90 = 190
