Question

If x+x/2+x/3+4=26 then x=

If 4x/5+3x/10+ab=a(a+b)+6a/5,*x=

Please help me out

Answer 1

Step-by-step explanation:

first one:

x+x/2+x/3+4=26

x+x+x+4=26×(2+3)=130

3x=130-4

x=126/3

x=42

second one:

4x/5+3x/10+ab=a(a+b)+6a/5, x=

4x/5+3x/10+ab=a²+ab+6a/5

4x/5+3x/10=a²+ab+6a/5-ab

4x+3x=a²+6a/5×15

4x+3x=a²+18a

7x=a²+18a

x=(a²+18a)/7
