Question

dont try to answer wrong​

Answer 1

Answer:

Step-by-step explanation:

q5a) 3(x+7)=18

3x+21=18

3x=18-21

3x= -3

x= -3/3

x= -1

q5b) 2(x-1)=x+2

2x-2=x+2

2x-x=2+2

x=4

q3) lets suppose sunils age as x and his father age will be 3x

10 years later sunils age will be x+10 and his fathers age will be 3x+10

2(3x+10)=x+10  

6x+20=x+10  

6x-x=10-20    

5x= -10      

x= -10/5

x= -2

i am not sure about 3 but i am sure as hell about q5 a and b but i am sorry about other question and i dont know how to solve them.

hope it helps ..

please mark as brainliest.
