Find the solution for this system of equations.
2x + 4y = 8
x = 3y - 6

x = 0 , y = 2

Step-by-step explanation:

Solve the following system:

{2 x + 4 y = 8 | (equation 1)

x = 3 y - 6 | (equation 2)

Express the system in standard form:

{2 x + 4 y = 8 | (equation 1)

x - 3 y = -6 | (equation 2)

Subtract 1/2 × (equation 1) from equation 2:

{2 x + 4 y = 8 | (equation 1)

0 x - 5 y = -10 | (equation 2)

Divide equation 1 by 2:

{x + 2 y = 4 | (equation 1)

0 x - 5 y = -10 | (equation 2)

Divide equation 2 by -5:

{x + 2 y = 4 | (equation 1)

0 x+y = 2 | (equation 2)

Subtract 2 × (equation 2) from equation 1:

{x+0 y = 0 | (equation 1)

0 x+y = 2 | (equation 2)

Collect results:

{x = 0 , y = 2

spinning a 1, 2, or 3. option d.

step-by-step explanation: when spinning a number graph up to 4, and aiming for any number less than 3, that automatically eliminates the number 4. now you have two numbers to spin on that are less than 3, but the number 3 is included in this question because it's no greater of an number than itself. i hope this you : )

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
