Simplify with multiplication.
You can't simplify further by adding, so leave the answer as-is.
Answer:
Negative
Step-by-step explanation:
It would be -1.3. Because you know? You add?
Answer:
I think it is 24 cus it's more bigger and cooler and hotter and shorter and butter
In parallelograms, opposite sides are congruent, meaning that they are the same lengths. So, we have:
y - 4x = 9
-x + 4 = y
Add x to both sides of the second equation:
y + x = 4
y - 4x = 9
This is a system of linear equations. Solve by eliminating the y and subtracting the two equations:
5x = -5
x = -1
Use x to solve for y:
y + (-1) = 4
y = 5
So, x = -1 and y = 5.
