Multiply both sides of each linear equation by a power of 10 that is sufficiently large to clear the decimal.
Example: 0.34x = 13.6.
There are two places to the right of the decimal point, on the left side; there is one place to the right of the decimal point, on the right side.
If you multiply both sides by 100, you get
34x = 1,360.
That result clears all decimals, and you might find it easier to solve. You don't have to do that, but many will say that that makes it easier for them.
To make them look more familiar and approachable to beginning algebra students. It's completely unnecessary with the advent of calculators though.
To solve it by coordinate graphs you would take a point from the line and plug in the X and Y value into the equations and or inequalities.
Yes
Somewhat, but the rules are a bit different for inequalities. Example. -2X > 4 X < - 2 See, sign changes when dividing by negative coefficient.
The question contains two equations:5x - 6y = 15 5x + y = 2 There are no inequalities in the question.
It makes it allot less confusing. But, that is just my opinion.
Even if you keep the decimal, later on you will still have to remove it. It is just an easier way to solve the equation.
Solving linear systems means to solve linear equations and inequalities. Then to graph it and describing it by statical statements.

There are many simple questions in everyday life that can be modelled by linear equations and solved using linear programming.
To solve it by coordinate graphs you would take a point from the line and plug in the X and Y value into the equations and or inequalities.
They are not. An inequality cannot, by definition, be the same as an equation.
Yes
Linear equations or inequalities describe points x y that lie on a circle.
Because linear equations are based on algebra equal to each other whereas literal equations are based on solving for one variable.
Solving linear equations is hard sometimes.
because you just do!
