Answer:
ddddddddddddddddddddddddddddddd
You're solving for variable 'X'.
Move all terms containing X to the left, all other terms to the right.
Add '-3Y' to each side of the equation.
7X + 3Y + -3Y = 0 + -3Y
Combine like terms:
3Y + -3Y = 0
7X + 0 = 0 + -3Y
7X = 0 + -3Y
Remove the zero:
7X = -3Y
<span>Divide each side by
'7'.
X = -0.4285714286Y
</span><span>Simplifying
X = -0.4285714286Y</span>
Answer:
4x − 10
Step-by-step explanation:
The width of rectangle A is 2x+4 and the length of rectangle A is x-1. This makes the perimeter
2(2x+4)+2(x-1)
= 4x+8+2x-2
= 6x+6
The width of rectangle B is 3x+1 and the width of rectangle B is 2x-3. This makes the perimeter
2(3x+1)+2(2x-3)
= 6x+2+4x-6
= 10x-4
Subtracting Perimeter B - Perimeter A, we ahve
(10x-4)-(6x+6)
= 10x-4-6x-6
= 4x-10
