Find two consecutive whole numbers such that 4/7 of the larger exceeds 1/2 of the smaller by 5

Respuesta :

Answer:

The consecutive numbers are 62 and 63

Step-by-step explanation:

Let the larger number be represented by x and the smaller number by y,

Provided they are consecutive numbers;

[tex]x = y + 1[/tex] --- Equation 1

From the question; we have that

[tex]\frac{4x}{7} = \frac{y}{2} + 5[/tex] --- Equation 2

Required

Find x and y

Multiply both sides of equation 2 by 14

[tex]14 * \frac{4x}{7} = 14 * \frac{y}{2} + 14 * 5[/tex]

[tex]2 * 4x = 7 * y + 70[/tex]

[tex]8x = 7y + 70[/tex] ---- Equation 3

Substitute y + 1 for x in equation 2

[tex]8(y + 1) = 7y + 70[/tex]

Open bracket

[tex]8y + 8 = 7y + 70[/tex]

Collect like terms

[tex]8y - 7y = 70 - 8[/tex]

[tex]y = 62[/tex]

[tex]x = y + 1[/tex]

So,

[tex]x = 62 + 1[/tex]

[tex]x = 63[/tex]

Hence, the consecutive numbers are 62 and 63
