NCERT Solutions for Class 8 Maths Chapter 2 Linear Equations In One Variable Ex 2.5
Solve the following equations:
Ex 2.6 Class 8 Maths Question 1.
\(\frac { 8x-3 }{ 3x } =2\)
Solution:
Ex 2.6 Class 8 Maths Question 2.
\(\frac { 9x }{ 7-6x } =15\)
Solution:
Ex 2.6 Class 8 Maths Question 3.
\(\frac { z }{ z+15 } =\frac { 4 }{ 9 } \)
Solution:
Ex 2.6 Class 8 Maths Question 4.
\(\frac { 3y+4 }{ 2-6y } =\frac { -2 }{ 5 } \)
Solution:
Ex 2.6 Class 8 Maths Question 5.
\(\frac { 7y+4 }{ y+2 } =\frac { -4 }{ 3 } \)
Solution:
Ex 2.6 Class 8 Maths Question 6.
The ages ofHari and Harry are in the ratio 5: 7. Four years from now the ratio of their ages will be 3 :4. Find their present ages.
Solution.
Let the present ages of Hari and Harry be 5x years and 7x years respectively.
∴ Present age of Hari =5 x 4 years = 20 years
∴ Present age of Harry =7 x 4 years = 28 years.
Ex 2.6 Class 8 Maths Question 7.
The denominator of a rational number is greater than its numerator by 8. If the numerator is increased by 17 and the denominator is decreased by 1, the number obtained is \(\frac { 3 }{ 2 } \). Find the rational number.
Solution.
Let the numerator of the rational number be x. Then, the denominator of the rational number = x + 8.
∴ The rational number = \(\frac { x }{ x+8 } \)
If the numerator is increased by 17 and the denominator is decreased by 1, the number becomes \(\frac { 3 }{ 2 } \).
Hence, the required rational number = \(\frac { 13 }{ 21 } \).
