Solved Examples and Worksheet for Writing Linear Equations

Q1Which of the following choices represents the phrase "3 added to 5 times x is equal to 19"?

A. 5x - 3 = 19
B. 5(x + 3) = 19
C. x3 + 3 = 19
D. 3 + 5x = 19

Step: 1
5 times x = 5x
Step: 2
3 added to 5x = 3 + 5x
  [Add 3 to 5x.]
Step: 3
3 added to 5 times x is equal to 19 is 3 + 5x = 19.
Correct Answer is :   3 + 5x = 19
Q2Choose an algebraic sentence for " Seven times the quantity of a number decreased by ten is equal to 186 more than the number". Let c be the number.

A. 7(c - 10) = 186 + c
B. 7(c - 10) > 186
C. 7c - 10 = 186c
D. 7c + 10 = 186 + c

Step: 1
Seven times the quantity of a number decreased by ten = 7(c - 10).
Step: 2
186 more than the number = 186 + c.
Step: 3
The algebraic sentence for the given word sentence: 7(c - 10) = 186 + c.
Correct Answer is :   7(c - 10) = 186 + c
Q3Which of the following choices represents the word phrase "4 added to 4 times x is equal to 19"?

A. x4 + 4 = 19
B. 4(x + 4) = 19
C. 4 + 4x = 19
D. 4x - 4 = 19

Step: 1
4 times x = 4x
Step: 2
4 added to 4x = 4 + 4x
  [Add 4 to 4x.]
Step: 3
4 added to 4 times x is equal to 19 is 4 + 4x = 19
Correct Answer is :   4 + 4x = 19
