Work Step by Step

Our two equations are: 1. x-7= y 2. 2x-y= 41 First lets substitute y in the first equation into the second equation. 2x-(x-7)=41 Simplify the equation: 2x-x+7=41 x+7=41 Subtract 7 from both sides of the equation to isolate x and find the value of it. x=34 Now lets substitute 34 as the x value into the first equation to find the value of y 34-7=y Simplify further: y=27 Therefore our coordinates to the answer of this system are: (34, 27)
