x +7. Plz explanation​

Answer 1

Answer:

3x + 5 =4x + 7

=)3x - 4x = 7 - 5

=)1x=2

=)x=2

x vale is 2

Answer 2

Answer:

We have, (3x + 5)/ (4x + 2) = (3x + 4)/(4x + 7) (3x + 5)/ (4x + 2) – (3x + 4)/(4x + 7) = 0 By taking LCM as (4x + 2) (4x + 7) ((3x + 5) (4x + 7) – (3x + 4) (4x + 2)) / (4x + 2) (4x + 7) = 0 By cross-multiplying we get, (3x + 5) (4x + 7) – (3x + 4) (4x + 2) = 0 (3x + 5) (4x + 7) – (3x + 4) (4x + 2) = 0 12x2 + 21x + 20x + 35 – 12x2 – 6x – 16x – 8 = 0 19x + 35 – 8 = 0 19x = -27 x = -27/19 Now let us verify the given equation, (3x + 5)/ (4x + 2) = (3x + 4)/(4x + 7) By substituting the value of ‘x’ we get, (3(-27/19) +5) / (4(-27/19) + 2) = (3(-27/19) + 4) / (4(-27/19) + 7) (-81/19 + 5) / (-108/19 + 2) = (-81/19 + 4) / (-108/19 + 7) ((-81+95)/19) / ((-108+38)/19) = ((-81+76)/19) / ((-108+133)/19) 14/19 / -70/19 = -5/19 / 25/19 -14/70 = -5/25 -1/5 = -1/5 Hence, the given equation is

verified.
