Step-by-step explanation:

Q3) Solve:

(i) -8m - 2 = -10

(ii) 4x + 2x = 3 + 5

(iii) 4x - x + 5 = 8

(iv) 6x + 2 = 2x + 10

(v) 18 - (2a - 12) = 8a

(vi) 3x + 5 + 2x + 6 + x = 4x + 21

(vii) 3.5x - 9 - 3 = x + 1

(viii) 8x + 6 + 2x - 4 = 4x + 8

(ix) - m + (3m - 6m) = - 8 - 14

(x) 5x - 14 = x - (24 + 4x)

Solution 3:

(i) -8m - 2 = -10

-8m = -10+2

-8m = -8

m = 1

(ii) 4x + 2x = 3 + 5

6x = 8

x=\frac{8}{6}=\frac{4}{3}=1\frac{1}{3}x=68=34=131

(iii) 4x - x + 5 = 8

3x + 5 = 8

3x = 8 - 5

3x = 3

x = 1

(iv) 6x + 2 = 2x + 10

6x - 2x = 10 - 2

4x = 8

x = 2

(v) 18 - (2a -12) = 8a

18 - 2a + 12 = 8a

-2a -8a = -18 -12

-10a = -30

a = 3

(vi) 3x + 5 + 2x + 6 + x = 4x + 21

6x + 11 = 4x + 21

6x - 4x = 21 - 11

2x = 10

x = 5

(vii) 3.5x - 9 - 3 = x + 1

3.5x - x = 1 + 9 + 3

2.5x = 13

x=\frac{13}{2.5}=\frac{13\times10}{25}=\frac{26}{5}=5\frac{1}{5}x=2.513=2513×10=526=551

(viii) 8x + 6 + 2x - 4 = 4x + 8

10x + 2 = 4x + 8

10x - 4x = 8 - 2

6x = 6

x = 1

(ix) -m + (3m - 6m) = -8 -14

-m + 3m - 6m = -8 -14

-7m + 3m = -22

-4m = -22

m=\frac{-22}{-4}=\frac{11}{2}=5\frac{1}{2}m=−4−22=211=521

(x) 5x - 14 = x - (24 + 4x)

5x - 14 = x - 24 - 4x

5x + 4x - x = -24 + 14

9x - x = -10

8x = -10

x=\frac{-10}{8}=\frac{-5}{4}=-1\frac{1}{4}x=8−10=4−5=−141
