3x+y=7,x-y=1

Solution

3 x + y = 7, x - y = 1

Solution

x = 2, y = 1

Solution steps

[3 x + y = 7 x - y = 1]

Isolate

x

for

3 x + y = 7 : x = \frac{7 - y}{3}

Substitute

x = \frac{7 - y}{3}

[\frac{7 - y}{3} - y = 1]

Simplify

[\frac{7 - 4 y}{3} = 1]

Isolate

y

for

\frac{7 - 4 y}{3} = 1 : y = 1

For

x = \frac{7 - y}{3}

Substitute

y = 1

x = \frac{7 - 1}{3}

\frac{7 - 1}{3} = 2

x = 2

The solutions to the system of equations are:

x = 2, y = 1

g(0)=1,g(n)=g(n-1)-g(n-2)g(4)

g (0) = 1, g (n) = g (n - 1) - g (n - 2) g (4)

2 x + 2 y = 8, x + y = 4

2x+y=17,3x+2y=27

2 x + y = 17, 3 x + 2 y = 27

x + 1 x = 17 - 2 y, y = 2

2 x + y = 3, 2 x + 2 y = 2
