Chapter 3: Q.2 (page 161)

Which equation has no solution?

F. 4t-8=4(t-2)

G. 3(r-1)=2(2+r)

H. 6p+2+9p-4

I.7(s+1)=-3+7s

Short Answer

Expert verified

The correct solution for this question is F 4t-8=4(t-2).

Step by step solution

01

Step  1.  Apply the concept of solving the equation and identify the equation that has no solution.

In this, simply use the concept of determining which equation has no solution, by solving and identifying the equation whose left-hand side and the right-hand side expression is equal.

02

Step  2.  Solve and identify the equation

4t鈭�8=4(t鈭�2)4t鈭�8=4t鈭�8

03

Step  3.  Eliminating the options to get correct answer

F. 4t-8=4(t-2) This is the correct option because its L.H.S and R.H.S expression is equal.

G. 3(r-1)=2(2+r) This is the incorrect option because its L.H.S and R.H.S expression is not equal.

H. 6p+2+9p-4 This is the incorrect option because its L.H.S and R.H.S expression is not equal.

I. 7(s+1)=-3+7s This is the incorrect option because its L.H.S and R.H.S expression is not equal.
