Question

rmine if the following equation is linear.
$7x(y + 2) = 3 - 7y(9 - x)$
ver
\\(\circ\\) linear
\\(\circ\\) not linear

Explanation:

Step1: Expand both sides of equation

Left: $7x(y+2)=7xy+14x$
Right: $3-7y(9-x)=3-63y+7xy$

Step2: Subtract $7xy$ from both sides

$7xy+14x-7xy=3-63y+7xy-7xy$
Simplify: $14x=3-63y$

Step3: Rearrange to standard linear form

$14x+63y=3$
This fits $Ax+By=C$ (no $xy$ terms, variables to first power).

Answer:

Linear
