x+2y=2,6x=7-y

x + 2 y = 2, 6 x = 7 - y

x = \frac{12}{11}, y = \frac{5}{11}

Solution steps

[x + 2 y = 2 6 x = 7 - y]

Isolate

x

for

x + 2 y = 2 : x = 2 - 2 y

Substitute

x = 2 - 2 y

[6 (2 - 2 y) = 7 - y]

Isolate

y

for

6 (2 - 2 y) = 7 - y : y = \frac{5}{11}

For

x = 2 - 2 y

Substitute

y = \frac{5}{11}

x = 2 - 2 \cdot \frac{5}{11}

2 - 2 \cdot \frac{5}{11} = \frac{12}{11}

x = \frac{12}{11}

The solutions to the system of equations are:

x = \frac{12}{11}, y = \frac{5}{11}

x - 3 y = 9, 2 y + x = 4

4 x - 3 y = 18, 2 x + 5 y = - 4

y = 2 x, x + y = 12

n + 65 = 8, 7 n = 27

92 x - 3 y + 8 = 0, x - 4 y + 7 = 0
