How to solve -16x+2y=-2, y=8x-1 by using substitution

For this case we have the following system of equations:

To solve, we substitute the second equation in the first:

We apply distributive property to the terms within parentheses:

Equality is met, so for any value of x it will be fulfilled. Therefore, the system of equations has infinite solutions.

Infinite solutions

it is a secret for it not to be compromised sorry

step-by-step explanation:

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

step-by-step explanation:

formula

x = x1 + p/w(x2 - x1)

let the line segment ab with a(x1,y1) and b(x2,y2)

a point(x,y) divide ab in the ratio, 2: 3 the x coordinate can be written as

x = x1 + p/w(x2 - x1)

here p=2 and w = 2+3

therefore,

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

similarly y coordinate y = y1 + 2/5(y2 - y1)
