<em><u>Answer is below</u></em>
Step-by-step explanation:
<em><u>Always remember to simplify both sides of the equation.</u></em>
![326=5(8a+8)\\326=(5)(8a)+(5)(8)\\(Distribute)\\326=40a+40\\](https://tex.z-dn.net/?f=326%3D5%288a%2B8%29%5C%5C326%3D%285%29%288a%29%2B%285%29%288%29%5C%5C%28Distribute%29%5C%5C326%3D40a%2B40%5C%5C)
<em><u>Flip the equation</u></em>
![40a+40=326](https://tex.z-dn.net/?f=40a%2B40%3D326)
<em><u>Subtract 40 from both sides.</u></em>
![40a+40-40=326-40\\40a=286](https://tex.z-dn.net/?f=40a%2B40-40%3D326-40%5C%5C40a%3D286)
<u><em>Divide both sides by 40.</em></u>
![40a/40=286/40\\Answer:a=143/20 \\(decimal 7.15)](https://tex.z-dn.net/?f=40a%2F40%3D286%2F40%5C%5CAnswer%3Aa%3D143%2F20%20%5C%5C%28decimal%207.15%29)
Answer:
-20x -27 is the required expression.
Step-by-step explanation:
whenever we are to solve the system of equations by substitution method we have to write one variable in the form of other so as to get the value of unknowns
here, we are given two expressions:
![8x-y=-9](https://tex.z-dn.net/?f=8x-y%3D-9)
And ![4x-3y=-22](https://tex.z-dn.net/?f=4x-3y%3D-22)
We have to substitute x in terms of y because the equation should be equivalent to y we will put
in ![4x-3y=-22](https://tex.z-dn.net/?f=4x-3y%3D-22)
we will get:
![4x-3(8x+9)](https://tex.z-dn.net/?f=4x-3%288x%2B9%29)
![\Rightarrow 4x-24x-27](https://tex.z-dn.net/?f=%5CRightarrow%204x-24x-27)
is the expression we will get after expression equivalent to y.
