(i) 5x = 3x + 24
(ii) 81 +5=21 - 31
(iii) 7x - 10 = 4x +11
(iv) 4z + 3 = 6 + 22
(v) 2r - 1 = 14-
(vi) 6x + 1 = 3 (x - 1)+7
(vii) 2x - +1
(viii) 3 - 2 = 2
(ix)3(x + 1) = 12 + 4(x - 1)
(x) 2x - 5= 3(x - 5) (xi) 6 (1 - 4x) + 7 (2+5x) = 53
(xii) 3(x + 6) + 2(x + 3) = 64
(xiii) -- +8 = -1
(xiv) (x - 1) = x - 3

Answer 1

Answer:

1. 5x= 3x + 24

5x - 3x = 24

2x = 24

X = 12

2. 81 + 5 = 21-31

86 = -10

3. 7x-10= 4x+11

7x -4x = 11+10

3x = 21

X = 7

4. 4z +3 =6+22

4z = 6+22-3

4z =25

z = 25 upon 4.
