x = 10, y = 4
Step-by-step explanation:
Solve the following system:
{x - 2 y = 2 | (equation 1)
2 x + 4 y = 36 | (equation 2)
Swap equation 1 with equation 2:
{2 x + 4 y = 36 | (equation 1)
x - 2 y = 2 | (equation 2)
Subtract 1/2 * (equation 1) from equation 2:
{2 x + 4 y = 36 | (equation 1)
0 x - 4 y = - 16 | (equation 2)
Divide equation 1 by 2:
{x + 2 y = 18 | (equation 1)
0 x - 4 y = - 16 | (equation 2)
Divide equation 2 by - 4:
{x + 2 y = 18 | (equation 1)
0 x+y = 4 | (equation 2)
Subtract 2 * (equation 2) from equation 1:
{x+0 y = 10 | (equation 1)
0 x+y = 4 | (equation 2)
Collect results:
Answer: {x = 10, y = 4

Rearrange first equation
2y = x-2
X = 2y + 2
Plug in values
2 (2y+2) + 4y = 36
4y + 4 + 4y=36
8y+4 = 36
8y=32
Y=4
Solved for y, now plug in to find x.
2y=x-2
2 (4) = x - 2
8 = x-2
X = 10
