Question

2. Check whether the value given in the brackets is a solution to the given equation
or not
(a) n + 5 = 19 (n = 1) (b) 3n +5 = 19 (n = - 2) (c) 3n +5 = 19 (n = 2)
(d) 4p - 3 = 13 (p= 1) (e) 4p - 3 = 13 (p =-4) (f) 4p - 3 = 13 (p = 0)
3. Solve the following equations by trial and error method:
(i) 5p + 2 = 17
(ii) 3m - 14 = 4
4. Write equations for the following statements:
6) The sum of numbers x and 4 is 9. (ii) 2 subtracted from yis 8.
(ii) Ten times a is 70.
(iv) The number b divided by 5 gives 6.
(v) Three-fourth of tis 15.
(vi) Seven times m plus 7 gets you 77.
(vii) One-fourth of a number x minus 4 gives 4.
(viii) If you take away 6 from 6 times y, you get 60.
(x) If you add 3 to one-third of z, you get 30.
