Solve the following equations by systematic​

Answer 1

Answer:

1)x=4, 2)p=7, 3)m=10/7,

Step-by-step explanation:

Answer 2

Answer:

(i)- 3x-5=7

= 5-5+3x = 7+5 ( by adding all number 5 )

3x = 12

3x/3 = 12/3 ( by divide each side by 3 )

x = 4

(ii) = 13/2

(iii) = 10/7

(iv) = 43/5

(v) = -12

(vi) = -28
