8x+4y=-20 and -4x-8y=-20 solve each system by substitution

True [87]

8x + 4y = -20
4y = -20 - 8x
y = -5 -2x

-4x - 8y = -20
-4x - 8(-5-2x) = -20
-4x + 40 + 16x = -20
12x = -60
x = -5

8(-5) + 4y = -20
-40 + 4y = -20
4y = 20
y = 5

Find the solution of this system of equations <br> -6y=-50-4x <br> 5x-6y=-49

Maslowich

Answer:

<h2> $(1,\ 9)$ </h2>

Step-by-step explanation:

Rewrite the first equation

$-6y=-50-4x\\\\4x-6y=-50$

Now we have the following system of equations

$4x-6y=-50\\5x-6y=-49$

To solve the system of equations multiply the first equation by -1 and add it to the second equation

$-1*4x-(-1)*6y=-50*(-1)\\\\-4x+ 6y=50$

$-4x+ 6y=50$

+

$5x-6y=-49$

-----------------------------------

$x + 0 =1\\\\x=1$

Now substitute the value of x in any of the two equations and solve for y

$5(1)-6y=-49$

$5-6y=-49$

$-6y=-49-5$

$-6y=-54$

$y=\frac{54}{6}$

$y=9$

The solution is:

$(1,\ 9)$

Explain how using the expanded form 4,000 + 30 + 2 can help find the product of 5 and 4,032

belka [17]

5*4032=5*(4000+30+2)=5*4000+5*30+5*2, it helps to break down the number to smaller bits,
