(b)
On subtracting - 5 from both sides of the equation x + 5 = 10, we get
(i) x = 0
(ii) X = 15
(iii) 5 = x
(iv) x = -5
x = 7 is the solution of the equation
(i) % - 7 = 0
(ii) x + 7 = 0
(iv) –7= x
(iii) - 7 - x = 0
(d) Equation 5x + 7 = 0 and equation
(0) 7x+5=0
have same solution
(ii) 25x + 35 = 0
(iii) 5x - 7 = 0
(iv) 7-5=0
If a and b are two positive integers then the solution of the equation ax = b will
always be a
[NCERT Exemplar)
(i) positive number
(ii) negative number
(iii) 1
(iv) o
auntion is neither a fraction or an integer?
