Question

solve the following equations by trial and error method i) 5p+2=17 ii) 3m-14=14​

Answer 1

Answer:

5p=17-2

5p=15

p=15/5

p=3

Answer 2

Answer:

i. 3.

Step-by-step explanation:

i. 5p+2=17

substitute 1

5(1)+2=17

5+2=17

7 is not equal to 17.

so substitute 2

5(2)+2=17

10+2=17

12 is not equal to 17

so check with 3

5(3)+2=17

15+2=17

17=17

so our answer is 3 if we will substitute 3 we got 17.
