Describing Linear Relationships

So graphing a linear equation in fact only requires finding two pairs of values and drawing a line through the points they describe. All other points on the line will provide values for x and y that satisfy the equation. The graphs of linear equations are always lines.

Hi my lil bunny!

❧⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯☙

Answer = $\boxed {x - 2}$

$3x +1(2x-1)2-1(6x)$

= $\boxed {3x + 1 . ( 2x - 1 ) . 2 - 1 (6x) = x - 2}$

Steps :

$3x + 1 . (2x - 1) . 2 - 1 . (6x)$

Remove the parentheses : $(a) = a$

$= 3x + 1 * (2x- 1) * 2 - 1 * 6x$

Multiply the numbers : $1 * 2 = 2$

$= 3x + 2 ( 2x - 1 ) * 6x$

Multiply the numbers : $1 * 6 = 6$

$= 3x + 2 ( 2x - 1 ) -6x$

Expand: $2 (2x - 1) : 4x - 2$

$2 ( 2x - 1 )$

Apply the distributive law : $a (b - c) = ab - ac$

$a = 2, b = 2x, c = 1 \\= 2 * 2x - 2 * 1$

Simplify $2 * 2x - 2 * 1 : 4x - 2$

= $= 4x - 2$

$= 3x + 4x - 2 - 6x$

Simplify $3x + 4x - 2 - 6x : x - 2$

= $x - 2$

Ok so important numbers 42 ft, 2cm, 3 ft and lets take height as x

if 2cm=3ft than x cm= 42 ft
2 = 3
-------
x= 42
cross multiply divide
