Answer:
8
Step-by-step explanation:
(-11x/2 + 3) -2(-11x/4 -5/2)
= -11x/2 + 3 -(2*-11x/4) -(2*-5/2)
= -11x/2 + 3 -(-22x/4) -(-5)
= -11x/2 + 3 +22x/4 + 5
= -22x/4 + 22x/4 + 3 + 5
= 0 + 8
= 8
The pattern that matches your examples is ...
... a + (b + c) = (a + b) + c
Answer:
The value of the equation
.
Step-by-step explanation:
Consider the provided equation.
![W = 3x + 7y](https://tex.z-dn.net/?f=W%20%3D%203x%20%2B%207y)
We need to solve the provided equation for y.
Subtract 3x from both side.
![W-3x= 3x-3x+ 7y](https://tex.z-dn.net/?f=W-3x%3D%203x-3x%2B%207y)
![W-3x=7y](https://tex.z-dn.net/?f=W-3x%3D7y)
Divide both sides by 7.
![\frac{7y}{7}=\frac{W-3x}{7}](https://tex.z-dn.net/?f=%5Cfrac%7B7y%7D%7B7%7D%3D%5Cfrac%7BW-3x%7D%7B7%7D)
![y=\frac{W-3x}{7}](https://tex.z-dn.net/?f=y%3D%5Cfrac%7BW-3x%7D%7B7%7D)
Hence, the value of the equation is
.
