Question

13. FOLD is a rectangle. Its diagonal meet at point P.
Find x if DO = 2x +4, FL = 3x + 1.
​

Answer 1

Answer:

x is equal to 3

Step-by-step explanation:

DO =FL

2x +4=3x+1

2x - 3x = 1-4

-x=-3

x =3

Answer 2

we already know that

1. (diagonals of rectangle are equal)

2. (equation means equal to)

solution:

thus equation formed =

1) 2x+4 = 3x+1

2) now put no. with variables in L.H.S. of equal to sign and without variables on R.H.S. of equal to sign :

2x -3x = 1-4

3) solve both sides

method 1)-x= -3

cut the minus signs from both side

u get answer directly :

x =3

method 2)

x=-3/-1

= x =3

note: (solve by your personal preferences)
