Answer:

(w-12)(w+12)

Step-by-step explanation:

Using the identity

a^2-b^2=(a-b)(a+b)

now,

w^2-144=(w)^2-(12)^2=(w-12)(w+12)

Solve each system by substitution. y=3x+4 y=4x+7

Y_Kistochka [10]

We need to solve the following system by substituition:

$\begin{cases}y=3x+4 \\ y=4x+7\end{cases}$

To solve by substituition means that we need to isolate one variable in one of the equations and replace one expression with the other. This is done below:

$\begin{gathered} (3x+4)=4x+7 \\ 3x+4=4x+7 \\ 3x-4x=7-4 \\ -x=3 \\ x=-3 \end{gathered}$

Then we need to replace the value of "x" in any of the two equations.

$\begin{gathered} y=3\cdot(-3)+4 \\ y=-9+4 \\ y=-5 \end{gathered}$

The solution is (-3,-5).
