Equations

Solve the following system of equations:


6(x+7)+4(y-5)=12
2(x+y)-3(-2x+4y)=-44

Final Answer:

x =  -3
y =  2

Step-by-step explanation:

6(x+7)+4(y−5)=12 2(x+y)−3(−2x+4y)=−44  6⋅ (x+7)+4⋅ (y−5)=12 2⋅ (x+y)−3⋅ (−2⋅ x+4⋅ y)=−44  6x+4y=−10 8x−10y=−44  Pivot:Row1↔Row2  Row2−86​⋅ Row1→Row2 11.5y=23  y=11.523​=2 x=8−44+10y​=8−44+10⋅ 2​=−3  x=−3 y=2
