Answer:

(a) n+ 5 = 19 (n = 1)

if n is 1

1+5=19

6≠19

so value given in the brackets is not a solution

(b) n + 5 = 19 (n = -2)

-2+5=19

3≠19

so value given in the brackets is not a solution

(d) 4p - 3 = 13 (p = 1)

4(1)-3=13

4-3=13

1≠13

so value given in the brackets is not a solution

(e) 4p - 3 = 13 (p = - 4)

4(-4)-3=13

-16-3=13

-19≠13

so value given in the brackets is not a solution

(i)6p + 4 = 17

6(1)+4=16

10≠16

6(2)+4=16

16=16

therefore p is 2

(ii) 3m - 14 = 4

3(1) - 14 = 4

-11≠4

3(2) - 14 = 4

-8≠4

3(3) - 14 = 4

-5≠4

3(4) - 14 = 4

-2≠4

3(5) - 14 = 4

1≠4

3(6) - 14 = 4

4=4

therefore p=6

1. The sum of numbers and 4

let the 2 numbers be a and b

a+b=4

2. Ten times a is 70

10a=70

3. Three fourth of a number is 15.

let the number be a

3 \\ \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:   - \: a  = 15 \\ 4
