x=2y+1,2x-2y=4

Solution

x = 2 y + 1, 2 x - 2 y = 4

Solution

x = 3, y = 1

Solution steps

[x = 2 y + 1 2 x - 2 y = 4]

Substitute

x = 2 y + 1

[2 (2 y + 1) - 2 y = 4]

Simplify

[2 y + 2 = 4]

Isolate

y

for

2 y + 2 = 4 : y = 1

For

x = 2 y + 1

Substitute

y = 1

x = 2 \cdot 1 + 1

Simplify

x = 3

The solutions to the system of equations are:

x = 3, y = 1

5 x + 3 y = - 1, - 3 x + 4 y = - 24

4/x+3/y =1, 6/x-(16)/y =8

\frac{4}{x} + \frac{3}{y} = 1, \frac{6}{x} - \frac{16}{y} = 8
