Steps

Step 1 :To solve the given system of linear equations, we can use either substitution or elimination method. In this case, we will use the elimination method to find the values of x and y.

Step 2 :We will multiply the first equation by 3 and the second equation by 5 to make the coefficients of x in both equations equal with opposite signs, and then add the equations to eliminate x.

Step 3 :Multiplying the first equation by 3: 3(5x8y)=3(37) gives 15x24y=111.

Step 4 :Multiplying the second equation by 5: 5(3x7y)=5(25) gives 15x35y=125.

Step 5 :Adding the two new equations 15x24y+(15x35y)=111+125 to eliminate x gives 59y=236.

Step 6 :Solving for y gives y=4.

Step 7 :Substitute y=4 into the first original equation 5x8(4)=37 to find x.

Step 8 :Solving the equation 5x+32=37 gives x=1.

Step 9 :The solution to the system of equations is x=1 and y=4.

Step 10 :Final Answer: (1,4)
