Question

Solve the system of linear equations by substitution. 6x−9=y y=−3x

Answer 1

Answer:

x = 1

y =  - 3

Step-by-step explanation:

Answer 2

Answer:

$(1, -3)$

$y= -3$

$x= 1$

Step-by-step explanation:

$6x - 9 = y \\ y = - 3x \\ solve \: using \: comparison \: method$

$6x-9= -3x \\subtract \:6x\: from \:both sides$

$-9x= -9\\ divide\: both \:sides\: by \:-9$

$x= 1\\substitute \:the\: value \:of\: x \:into\: an \:equation$

$y= -3×1\\ multiply\: -3\: to\: 1$

$y= -3$

$(1,-3)$
