If you mean: -9x+4y = 8 and -3x+y = 4 then the solutions are x = -8/3 and y = -4

What is another name for a parallelogram with the same length and the same angles?
A SQUARE A rectangle satisfies the angles but not the lengths. A rhombus satisfies the length, but not the angles. A parallelogram neither satisfies length nor angles.
What does it mean both algebraically and graphically when an ordered pair is a solution to a system of two linear equations?
If an ordered pair is a solution to a system of linear equations, then algebraically it returns the same values when substituted appropriately into the x and y variables in each equation. For a very basic example: (0,0) satisfies the linear system of equations given by y=x and y=-2x By substituting in x=0 into both equations, the following is obtained: y=(0) and y=-2(0)=0 x=0 returns y=0 for both equations, which satisfies the ordered pair (0,0). This means that if an ordered pair is a solution to a system of equations, the x of that ordered pair returns the same y for all equations in the system. Graphically, this means that all equations in the system intersect at that point. This makes sense because an x value returns the same y value at that ordered pair, meaning all equations would have the same value at the x-coordinate of the ordered pair. The ordered pair specifies an intersection point of the equations.
Why is it important to do the same things to both sides of an equation?
In an equation, the left side has the same value as the right side. The importance of doing the same thing to both sides is to keep the value of both sides the same so the equation does not change.
What is having the same value in math?
It means having the same value is to be equivalent as for example 1/2 has the same value as 2/4 because they are both equivalent fractions.
What is greater 4.07 or 4.070?
They are both the same numerical value

which is bigger 9.90 or 9.9?
As given they are the same value, but...but...the 9.9 opens the possibility that the actual value is more or less than 9.90. In other words, because it lacks that zero on the end, it could be, say, 9.91 and someone just rounded it to 9.9.
Is 0.6800 the same as 0.680?
Yes, they both have the same value.

Is 0.05 the same as 0.050?
Yes, both numbers have the same value.
Expressions that have the same value?
If both equations can be simplified to the same value, they are equal.
Can numerical expressions have the same value?
Yes, numerical expressions can have the same value. For example, the expressions 2+3 and 5 both have the value of 5. Similarly, the expressions 2x3 and 6 both have the value of 6. In general, any two numerical expressions that evaluate to the same number will have the same value.
What is greater 5.50 or 5.5?
They are both the same value.
Which is bigger 5.2 or 5.20?
They are both the same value.
What is less 0.2 or 0.20?
They are both the SAME value.
What is bigger 7.3 or 7.300?
They both have the same value.
