Answer:
x = -73/9 , y = 1/3
Step-by-step explanation:
Solve the following system:
{3 x + 4 y = -23 | (equation 1)
2 = 3 y + 1 | (equation 2)
Express the system in standard form:
{3 x + 4 y = -23 | (equation 1)
0 x - 3 y = -1 | (equation 2)
Multiply equation 2 by -1:
{3 x + 4 y = -23 | (equation 1)
0 x+3 y = 1 | (equation 2)
Divide equation 2 by 3:
{3 x + 4 y = -23 | (equation 1)
0 x+y = 1/3 | (equation 2)
Subtract 4 × (equation 2) from equation 1:
{3 x+0 y = (-73)/3 | (equation 1)
0 x+y = 1/3 | (equation 2)
Divide equation 1 by 3:
{x+0 y = (-73)/9 | (equation 1)
0 x+y = 1/3 | (equation 2)
Collect results:
Answer: {x = -73/9 , y = 1/3
