Solve the system of linear equations by substitution.<br> 3x + y = -9<br> y=5x+7

11Alexandr11 [23.1K]

Answer:

The solution is x = -2, y = -3

Step-by-step explanation:

Let's start with the equation 3x + y = -9

Substitute the y for 5x+7 seen in the second equation

Now you have 3x + (5x+7) = -9

Lets solve:

Let's add the x's

Now we have 8x + 7 = -9

Substracy seven from each side

Now we have 8x = -16

Now let's divide 8 on each side

Now we have x = -2

Now lets plug in -2 to the second equation

The second equation is y = 5x+7

When we plug in -2 we get y=5(-2)+7

We multiply

We now have y = -10+7

Add

y = -3

The solution is x = -2, y = -3

What is the answer to the equation 3(x+4.5)=36?

kozerog [31]

Answer:

$x = 7.5$

Step-by-step explanation:

$3(x + 4.5) = 36$

$3x + 13.5 = 36$

$3x = 36 - 13.5$

$3x = 22.5$

$x = \frac{22.5}{3}$

$x = 7.5$
