Question

Mathematics for Class 6
2. Write a statement for each of the equations. given below:
(1) X-7 = 14
(ii) 2y = 18
(iil) 11 + 3x = 17
2 z
(iv) 2x - 3 - 13
=8
(vi)
(v) 12y - 30 = 6
3
3. Verify by substitution that
(1) the root of 3x 5 =7 is x = 4
(11) the root of 3 + 2x = 9 is x = 3
in the root of 5x - 8 = 2x - 2 is x = 2 (iv) the root of 8 - 7y = 1 is y = 1
(v) the root of
z
=8 is z = 56
7
4. Solve each of the following equations by the trial-and-error method:
(1) y + 9 = 13 (ii) x - 7 = 10 (iii) 4x = 28
1
(v) 11 + x = 19 (vi)
(vii) 2x - 3 = 9 (viii) x + 7 = 11
3
2
(ix) 2y + 4 = 3y (x) 2-3 = 2z - 5
(iv) 3y = 36
