2x = 5 + 4

2x = 9

x = 9/2

x = 4.5

Substitue "x" in equation 2

5x + 4y = 2

5(4.5) + 4y = 2

22.5 + 4y = 2

4y = 2 - 22.5

4y = -20.5

y = -20.5 / 4

y = -5.125

So x = 4.5, y = -5.125

2x = 9

x = 9/2

x = 4.5

Substitue "x" in equation 2

5x + 4y = 2

5(4.5) + 4y = 2

22.5 + 4y = 2

4y = 2 - 22.5

4y = -20.5

y = -20.5 / 4

y = -5.125

So x = 4.5, y = -5.125
