Question

3. 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)​

Answer 1

Answer:

1 Given, −8m−2=−10

−8m=−10+2

−8m=−8

m=−8/−8

We get,

m=1

Therefore, the value of m=

2 Given, 4x+2x=3+5

Given, 4x−x+5=8

3x=8−5

3x=3

x=3/3

We get,

x=1

Therefore, the value of x=16x=8

x=8/

We get,a

x=4/3

x=1

3 Given, 4x−x+5=8

3x=8−5

3x=3

x=3/3

We get,

x=1

Therefore, the value of x=1

4

5 Given, 18−(2a−12)=8a

18−2a+12=8a

30=8a+2a

30=10a

We get,

a=3

Therefore, the value of a=3
