Answer:

y = 8

Step-by-step explanation:

4y - 4 = 28

take -4 to the equal side, which will change and become +4

so, it will be; 4y = 28 + 4

4y = 32

divide both sides by the number next to the unknown(y), which is 4

y = 8

Answer:

Step-by-step explanation:

4y-4=28

4y=28+4

4y=32

y=32/4

y=8

now plug in 8 for y and check the equation true:

4y-4=28

4*(8)-4=28

32-4=28

28=28

So, y is equal to eight 8

How do you solve each system by graphing

abruzzese [7]

See the attached graph

<h2>Explanation:</h2>

Hello! Remember to write complete questions in order to get good and exact answers. Here you don't provide any system so I couldn't help you in an exact way, but in a general manner. When solving systems by graphing we just need to find the points of intersection of the graphs of the functions that built up the system.

Suppose you have the following system of linear equation:

$\left\{ \begin{array}{c}y=2x+3\\3y=8x+27\end{array}\right.$
