Question

simplify these expression and find their values if x=3, a=-1,b=2 (a) 3x-5-x=9​​

Answer 1

Answer:

given

givenx=3,

givenx=3, a=-1,

givenx=3, a=-1,b=2

givenx=3, a=-1,b=2 3x-5-x=9

put x=3

3×3 - 5 - 3 = 9-5-3 =9-8=1

which is not equal to 9 so

x= 3 is not true

put x=a= -1

-3-5+1= -8+1 = -7

not true also

put x= b= 2

6-5-2 = 6-10 is not true
