Answer:

x = 3 , y = 1

Explanation:

Solve the following system:

{4 x - 3 y = 9 | (equation 1)

10 y = 2 x + 4 | (equation 2)

Express the system in standard form:

{4 x - 3 y = 9 | (equation 1)

-(2 x) + 10 y = 4 | (equation 2)

Add 1/2 × (equation 1) to equation 2:

{4 x - 3 y = 9 | (equation 1)

0 x+(17 y)/2 = 17/2 | (equation 2)

Multiply equation 2 by 2/17:

{4 x - 3 y = 9 | (equation 1)

0 x+y = 1 | (equation 2)

Add 3 × (equation 2) to equation 1:

{4 x+0 y = 12 | (equation 1)

0 x+y = 1 | (equation 2)

Divide equation 1 by 4:

{x+0 y = 3 | (equation 1)

0 x+y = 1 | (equation 2)

Collect results:

Answer: {x = 3 , y = 1
