Find the solution of the system of equations.6x + 8y = -8x + 4y = 4( , )

Answer:

the solution is (-4, 2)

Step-by-step explanation:

6x + 8y = -8

x + 4y = 4

... can be solved using elimination by addition and subtraction, among other methods. Multiply the second equation by -2 to obtain

6x + 8y = -8

-2x - 8y = -8

Combining these results in

4x = -16. Thus, x = -4.

Substituting -4 for x in x + 4y = 4 results in

-4 + 4y = 4, or 4y = 8, or y = 2

Then the solution is (-4, 2)

Using the distributive property

$7(a+b)=7a+7b$

therefore

<u>the answer Part A is</u>

$9-----> A$

<u>Part R)</u> $4(5+x)=20+$

Using the distributive property

$4(5+x)=20+4x$

therefore

Using the distributive property

$a(4+b)=4a+ab$

therefore

<u>the answer Part O is</u>

$17-----> O$

<u>Part E)</u> $x(y+10)=+10x$

Using the distributive property

$x(y+10)=xy+10x$

therefore

<u>the answer Part E is</u>

$3-----> E$

<u>Part I)</u> $2(7x+4y)=14x+$

Using the distributive property

$2(7x+4y)=14x+8y$

therefore

<u>the answer Part I is</u>

$20-----> I$

<u>Part D)</u> $6(9+5x)=54+$

Using the distributive property

$6(9+5x)=54+30x$

therefore

<u>the answer Part D is</u>

$10-----> D$

<u>Part W)</u> $x(a+3b)=+3bx$

Using the distributive property

$x(a+3b)=ax+3bx$

therefore

<u>the answer Part W is</u>

$18-----> W$

<u>Part E)</u> $a(8x+2y)=8ax+$

Using the distributive property

$a(8x+2y)=8ax+2ay$

therefore

<u>the answer Part E is</u>

$7-----> E$

<u>Part T)</u> $0.5(4a+10)=2a+$

Using the distributive property

<u>Part T)</u> $0.5(4a+10)=2a+5$

therefore

<u>the answer Part T is</u>

$1-----> T$

<u>Part R)</u> $(2/3)(12+9y)=8+$

Using the distributive property

$(2/3)(12+9y)=8+6y$

therefore

There are 7/8 kilograms of salt in the kitchen. Mrs. Jackson used 2/15 of salt when preparing dinner . How much salt did she use

neonofarm [45]

so since Mrs Jackson used 2/15 of 7/8, the amount she used is simply their product.

$\bf \stackrel{\textit{how much is }\frac{2}{15}\textit{ of }\frac{7}{8}?}{\cfrac{7}{8}\cdot \cfrac{2}{15}}\implies \cfrac{7}{15}\cdot \cfrac{2}{8}\implies \cfrac{7}{15}\cdot \cfrac{1}{4}\implies \cfrac{7}{60}$
