Question

Y+7=2(x+5) in standard form ​

Answer 1

Answer:

$2x-y=-3$

Step-by-step explanation:

$\mathrm{The\: standard\: form\: of\: a \:linear \:equation \:is}:\mathrm{A}x+\mathrm{B}y=\mathrm{C.}$

$\underline{\sf{Solve\:for\:}y}:$

$y+7=2(x+5)$

$=y+7=2x+2\cdot5$

$= y+7=2x+10$

$=(y+7)+(-7)=(2x+10)+(-7)$

$=y+7-7=2x+10-7$

$\underline{y=2x+3}$
