Solve the system of linear equations using elimination. −7x + 3y = −6 −3x + 3y = 6

Question
Answer:
Answer:x = 3 , y = 5Step-by-step explanation:Solve the following system: {3 y - 7 x = -6 | (equation 1) 3 y - 3 x = 6 | (equation 2) Subtract 3/7 × (equation 1) from equation 2: {-(7 x) + 3 y = -6 | (equation 1) 0 x+(12 y)/7 = 60/7 | (equation 2) Multiply equation 2 by 7/12: {-(7 x) + 3 y = -6 | (equation 1) 0 x+y = 5 | (equation 2) Subtract 3 × (equation 2) from equation 1: {-(7 x)+0 y = -21 | (equation 1) 0 x+y = 5 | (equation 2) Divide equation 1 by -7: {x+0 y = 3 | (equation 1) 0 x+y = 5 | (equation 2) Collect results: Answer:  {x = 3 , y = 5
