Question

Solve and verify : 2x+7=3(x-1)​

Answer 1

Answer:

x = 10

Step-by-step explanation:

given -

2x + 7 = 3(x-1)

to find -

the value of x

solution -

2x +7 = 3(x-1)

=> 2x +7 = (3×x) - (3×1)

=> 2x +7 = 3x -3

=> 2x = 3x -3 -7

=> 2x-3x = -10

=> -x = -10

=> -x×(-1) = (-10)×(-1)

=> x = 10

Hence value of x is 10.

to prove (verify)

p(x) =

2x +7 = 3(x-1)

p(10) =

2(10) +7 = 3(10-1)

=> 20+7 = 3(9)

=> 27 = 27

=> LHS = RHS

proved (verified)

hope it helps.

Answer 2

Step-by-step explanation:
