Answer:

What's a Solution to a System of Linear Equations? Note: If you have a system of equations that contains two equations with the same two unknown variables, then the solution to that system is the ordered pair that makes both equations true at the same time.

Answer: x = 4 and y = -3

Step-by-step explanation:

2x + 4y = -4

2x = -4 - 4y

x = -2 - 2y

Now that we have solved the first equation for x, we plug (-2 - 2y) into the other equation in place of x and then solve for y.

3(-2 -2y) + 5y = -3

-6 - 6y + 5y = -3

-y = 3

y = -3

Now that we know y, we plug it into the original equation and solve for x.

2x + 4(-3) = -4

2x + -12 = -4

2x = 8

x = 4

You can check the answer by plugging both x and y into either of the original equations.

The size of the angle of a triangle are are in the ratio 2:4:9 calculate the size of the three angles in degree
solmaris [256]
Total Unit of Triangle = 2+4+9 = 15
Value of one unit = 180/15 = 12

So, Angles = 2(12) : 4(12) : 9(12) = 24 : 48 : 108

In short, Your Angles would be: 24, 48 & 108

Hope this helps!
