Answer:

x = 70/9 :)

Step-by-step explanation:

So, 9(x - 9) = -11. :)

We can use the distributive property to turn 9(x - 9) into 9x - 81!

9x - 81 = -11

We can now add on 81 to both sides :)

9x = -11 + 81 = 70

So, we have 9x = 70.

To get x by itself, we'll divide the equation by 9, to get:

9x / 9 = 70 / 9

x = 70/9

And there's your solution :)

Answer:

Hence the expression $(m+11)(m-4)=m^2+7m-44$

Step-by-step explanation:

Explanation

The given expression is (m+11)(m-4).
We have to multiply the given expression.
Multiply the (m+11) by -4, multiply the (m+11) by m then add like terms.

$$$\frac{\begin{matrix}{} & {} & m & + & 11 \\ \times & {} & m & - & 4 \\ \end{matrix}}$

_____________

${\frac{\begin{matrix}{} & - & 4m & - & 44 \\ {{m}^2} & + & 11m & {} & {} \\ \end{matrix}}{\begin{matrix}{{m}^2} & + & 7m & - & 44 \\ \end{matrix}}}$$$

Solve the system of equations by elimintion express the solution as and order paired

tester [92]

First convert the first equation to combine like terms. Then set your equations up as an addition problem. You want at least one of your variables (y) to be of opposite values so the will cancel out to leave you with just one variable (x). Plug in 1/3 for the x into one of the equations to solve for y. Then write as an ordered pair.
