2.Write any four solutions for5x–2=0.

3.If(3,1)is a solution of thenequation3x+2y=k,thenfind k.

4.Verifythatx=2,y=-1isasolutionofthelinearequation7x+3y=11.

5.Thecost of 2 pencils is same as the cost of 5 erasers.Express the statement as a

pls tell correct answer for this 5 questions pls ​

Answer 1

Answer:

1. 3
2. 1. 5x=2 2. x=2/5 3. 5x-2=0 4.-x=-2/5
3. 3×3+2×1=k=9+2=k=11
4. put value of x and y in eq 7x +3y=11

7(2)-3=11 14-3=11 11=11 hence proved

5. 2x =2y

2x-2y=0

x-y=0
