Answer :
2x+14=18 is the correct linear equation.
Math word problems is one of the most complex parts of the elementary math curriculum since translating text into symbolic math is required to solve the problem. Because the Wolfram Language has powerful symbolic computation ability, Wolfram|Alpha can interpret basic mathematical word problems and give descriptive results.A word problem in maths is a maths question written as one sentence or more that requires children to apply their maths knowledge to a ‘real-life’ scenario.
This means that children must be familiar with the vocabulary associated with the mathematical symbols they are used to, in order to make sense of the word problem.
Let x be the number of days he has been doing sit-ups, not counting the first day. Since he does 2 more sit-ups for each day, then the number of additional sit-ups is 2x.
Since he started doing 15 sit-ups on the first day, the total number of sit-ups after xx days would be 2X +15.
Since he did a total of 18 sit-ups today, then 2x+14=18.
