63x-14y=75,66x+14y=210

63 x - 14 y = 75, 66 x + 14 y = 210

x = \frac{95}{43}, y = \frac{1380}{301}

Solution steps

[63 x - 14 y = 75 66 x + 14 y = 210]

Isolate

x

for

63 x - 14 y = 75 : x = \frac{75 + 14 y}{63}

Substitute

x = \frac{75 + 14 y}{63}

[66 \cdot \frac{75 + 14 y}{63} + 14 y = 210]

Simplify

[\frac{602 y + 1650}{21} = 210]

Isolate

y

for

\frac{602 y + 1650}{21} = 210 : y = \frac{1380}{301}

For

x = \frac{75 + 14 y}{63}

Substitute

y = \frac{1380}{301}

x = \frac{75 + 14 \cdot \frac{1380}{301}}{63}

\frac{75 + 14 \cdot \frac{1380}{301}}{63} = \frac{95}{43}

x = \frac{95}{43}

The solutions to the system of equations are:

x = \frac{95}{43}, y = \frac{1380}{301}

9 x + 6 y = 51, 14 x - 7 y = 14

x + \frac{6}{y} = 6, 3 x - \frac{8}{y} = 5

x + y = 10, x = y + 4

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

5 x - y = 10, x + 2 y = 2
