What is the value of y in the solution to the following system of linear equations?

Leviafan [203]

ANSWER

$y=12$

<u>EXPLANATION</u>

One way is to make x the subject in one equation and substitute into the other.

$2x+2=y$

$\Rightarrow 2x=y-2$

$\Rightarrow x=\frac{y}{2}-1--(1)$

The second equation is

$2y=5x-1--(2)$

Let us put equation 1 in 2

$\Rightarrow 2y=5(\frac{y}{2}-1)-1$

$\Rightarrow 2y=\frac{5y}{2}-5-1$

$\Rightarrow 2y=\frac{5y}{2}-6$

Multiplying through by 2 gives;

$\Rightarrow 4y=5y-12$

$\Rightarrow 4y-5y=-12$

$\Rightarrow -y=-12$

$\Rightarrow y=12$
