Question

3. Solve the following equations and check the
solutions obtained.
(i) 3x - 2 = 22
(ii) 5m + 7 = 17
30p
(iii) = 60
(iv) 4p + 4 = 20
2
(v) 29 + 6 = 0
(vi) 3(x + 2) = 6
9x
(vii) - 4 = 14 (viii) 4(m + 3) = 20
2
(ix) - 2(x + 3) = 8 (x) 7 + 3(x - 2) = -2
(xi) 5(3x + 4) - 3 = 47 (xii) 7(2x - 1) + 5 = 54​

Answer 1

I 3x-2=22

3x=22+2

3x=24

x=24/3

x=8(ans)

ii 5m+7=17

5m=17-7

5m=10

m=10/5

m=2(ans)

iii. 30p=60

p=60/30

p=2(ans)

iv. 4p+4=20

4p=20+4

4p=24

p=24/4

p=6
