Answer

x=2,y=16

Steps

Step 1 :Substitute the expression for y from the second equation into the first equation: 2x+(6x+4)=20

Step 2 :Simplify the equation: 8x+4=20

Step 3 :Solve for x: 8x=16 and x=2

Step 4 :Substitute the value of x back into the second equation to find the value of y: y=6(2)+4

Step 5 :Solve for y: y=12+4 and y=16

Step 6 :x=2,y=16
