What is the solution to the system of equations below?

Free_Kalibri [48]

Answer: Infinite solutions.

Step-by-step explanation:

$y=-2x-6\\2y=-4x-12$

Plug the value of y into the second equation.

$\\ 2(-2x-6)=-4x-12\\-4x-12=-4x-12$

Add 12 on both sides.

$-4x-12+12=-4x-12+12\\-4x=-4x$

Add 4x on both sides.

$-4x+4x=-4x+4x$

$0=0$

Step-by-step explanation:

Step 1: Define Systems

y = 2x - 7

y = -x + 5

Step 2: Solve for x

Substitution

Substitute in y: 2x - 7 = -x + 5
[Addition Property of Equality] Isolate x terms: 3x - 7 = 5
[Addition Property of Equality] Isolate x term: 3x = 12
[Division Property of Equality] Isolate x: x = 4

Step 3: Solve for y

Define original equation: y = -x + 5
Substitute in x: y = -4 + 5
Add: y = 1

PLEASE SHOW YOUR WORK WITH YOUR ANSWER. Two bags had 50 kilograms of sugar each. After taking out 3 times as much sugar from bag

Svetllana [295]

Answer:

Bag 1: 20

Bag 2: 40

Step-by-step explanation:

Let x be the amount taken out of bag 2

Then the amount left in each bag can be written as:

Bag 1: 50-3x

Bag 2: 50-x

Since we know that half of bag 2 is bag 1, that gives us:

50-3x = 1/2(50-x)

-> 50-3x = 25-x/2

Now lets isolate x and solve:

25 = 5x/2

-> 50 = 5x

-> x = 10

So plug x bag in for the original equations:

Bag 1: 50-3x = 50-3(10) = 20

Bag 2: 50-x = 50-10 = 40
