I'm solving your system by substitution.

2x-4=5, 5x+4y =2

Step# 1: solve for x

2x - 4+ 4= 5 + 4( add +4 to both sides)

2x = 9

x = 9/2

Step# 2: solve for y

5(9/2) + 4y = 2

4y + 45/2 = 2

4y 45

y = 45/4 = 11.25

2x-4=5, 5x+4y =2

Step# 1: solve for x

2x - 4+ 4= 5 + 4( add +4 to both sides)

2x = 9

x = 9/2

Step# 2: solve for y

5(9/2) + 4y = 2

4y + 45/2 = 2

4y 45

y = 45/4 = 11.25
