Question

09. Find the solution of the equation from the values given in the bracket. Also, show
that the other values do not satisfy the equation.
2y - 3 = 7 (0,3,5,7)​

Answer 1

Answer:

y = 5

                                                                                         

Step-by-step explanation:

Given,

2y - 3 = 7

2y = 7 + 3 = 10

2y = 10

y = 5

∴ Solution = 5

                                                                                         

TP: 0, 3, 7 can't be the solution.

If y = 0, 2(0) -3 = -3 $\neq$ 7

If y = 3, 2(3) -3 = 6 - 3 =3 $\neq$ 7

If y = 7, 2(7) -3 = 14 - 3 = 11 $\neq$ 7

                                                                                         

Answer 2

Answer:

y=5

Step-by-step explanation:

2y-3=7

2y=10

y=5

when y=0 then l.h.s≠r.h.s

when y=3 then l.h.s≠rhs

when y=7 then lhs≠rhs
