Answer:
y = 3/2
, x = 3/2
Step-by-step explanation:
Solve the following system:
{x + y = 3 | (equation 1)
10 x = 15 | (equation 2)
Divide equation 2 by 5:
{y + x = 3 | (equation 1)
0 y+2 x = 3 | (equation 2)
Divide equation 2 by 2:
{y + x = 3 | (equation 1)
0 y+x = 3/2 | (equation 2)
Subtract equation 2 from equation 1:
{y+0 x = 3/2 | (equation 1)
0 y+x = 3/2 | (equation 2)
Collect results:
Answer: {y = 3/2
, x = 3/2
