The area of a rectangle increases by 200 sq m if the length is increased by 8 m and the breadth is increased by 3 m. The area increases by 255 sq m if the length is increased by 3 m and the breadth is increased by 8 m. Find the length of the rectangle

A linear equation is an algebraic equation that involves a constant and a first-order term. The equation is written as y=mx+b, where m is the slope and b is the y-intercept.  Here are some examples of linear equations: y = 3 + 2x y = -0.01 + 1.2x y = 25 + 20x 2x + y - 3 = 0  The graph of a linear equation is a straight line. The slope of a line is the amount by which it rises or falls. It is calculated by the formula rise/run.  Here are some steps for solving linear equations: Expand brackets Group like terms together Simplify the equation Remove constants from the variable Check...

A linear equation is an algebraic equation that involves a constant and a first-order term. The equation is written as y=mx+b, where m is the slope and b is the y-intercept. 

Here are some examples of linear equations:
y = 3 + 2x
y = -0.01 + 1.2x
y = 25 + 20x
2x + y - 3 = 0 

The graph of a linear equation is a straight line. The slope of a line is the amount by which it rises or falls. It is calculated by the formula rise/run.

Linear equations can be used for many real-world applications, such as:
Calculating the outside temperature from the number of times crickets chirp in one minute
Figuring out how fast a projectile is moving
Converting one unit of measure to another
Calculating rates, such as how quickly a chemical reaction is proceeding.
