How to work out this linear stimultaneous equations

Oduvanchick [21]

Step-by-step explanation:

extract the third equation from one of the given equation by making at most one variable with 1 as the coefficient the subject of the equation.
$x = 2 - y...........(3)$
now substitute the third equation to the other equation *Not the one you extracted the new equation from*
$y = 2 ({2 - y})^{2} + (2 -y ) - 2$
After substituting simplify
$y = 2(2 - y)(2 - y) + 2 - y - 2 \\ y = 2(4 - 2y - 2y + {y}^{2} ) + 2 - y - 2 \\ y = 2(4 - 4y + {y}^{2} ) - y \\ y = 8 - 8y + 2 {y }^{2} - y$
Therfore group the terms in the form of a general Quadratic equation.

Given the equation 5(-2x -10) = 25(x + 1), solve for the value of x that will make the equation true.

brilliants [131]

Answer:

Step-by-step explanation:

5(-2x -10) = 25(x + 1)

-10x - 50 = 25x + 25

by transposing

-10x - 25x = 25 + 50

-35x = 75

x = -75/35

x = 15/7

or 2.142857..... in decimal

Hope this helps
