Question

4. Solve for x and y:
11x + 15y + 23 = 0 and 7x - 2y - 20 = 0​

Answer 1

Answer:

given equations 1 &2

Step-by-step explanation:

multiply equation 1 with 2

and equation 2 with 15 we get

22x+30y+46=0

105x-30y-300=0 by solving these equations we get

127x-254=0

127x=254

x=254/127

x=2
