Solve and verify​

Answer 1

Answer:

your answer =7

Step-by-step explanation:

(3x+5)-(x+4)=15

3x+5-x-4=15

3x-x+5-4=15

2x+1=15

2x=15-1

2x=14

x=14/2

x=7 Ans

i hope it may help you

Answer 2

Step-by-step explanation:

(3x+5)-(x+4)=15

=> 3x + 5 - x - 4 = 15

=> 2x + 1 = 15

=> 2x = 15-1

=> 2x = 14

=> x = $\frac{14}{2}$

=> x = 7(Ans)

Now by putting the value of x= 7

LHS = (3x+5) - (x+4)                     RHS = 15

       =  (3×7+5)-(7+4)

       = 26 - 11

       = 15

∵ LHS = RHS , verified.
