Question

( 2y + 9 ) = 15 if y = 3 check whether the value given in the brackets in the solution to the given equations or not​

Answer 1

Step-by-step explanation:

we have,

(2y+9) = 15

by putting y = 3

(2×3+9) = 15

6+9 = 15

so, 15 = 15

it is true ....

Answer 2

Answer:

yes the value of y = 3  when opening the bracket give 15

Step-by-step explanation:

(2y + 9 ) = 15

if y = 3

then

                       LHS                                                           RHS

                    2  × 3 + 9                                                       15

                    15                             =                                  15

                                            LHS = RHS

                                       HENCE PROVED

that the value of y is correct or the equation given is correct
