x-3y-3=3,x-9y-2=0

Solution

x - 3 y - 3 = 3, x - 9 y - 2 = 0

Solution

x = 8, y = \frac{2}{3}

Solution steps

[x - 3 y - 3 = 3 x - 9 y - 2 = 0]

Isolate

x

for

x - 3 y - 3 = 3 : x = 3 y + 6

Substitute

x = 3 y + 6

[3 y + 6 - 9 y - 2 = 0]

Simplify

[- 6 y + 4 = 0]

Isolate

y

for

- 6 y + 4 = 0 : y = \frac{2}{3}

For

x = 3 y + 6

Substitute

y = \frac{2}{3}

x = 3 \cdot \frac{2}{3} + 6

3 \cdot \frac{2}{3} + 6 = 8

x = 8

The solutions to the system of equations are:

x = 8, y = \frac{2}{3}

2 x + y = - 10, x - 3 y = 2

2 x + 3 y = 7, 3 x - y = 5

4 x + 2 y = 8, 3 x - y = 1

4x-4=10,5x+2y=14

4 x - 4 = 10, 5 x + 2 y = 14

x+y=13,70x+80y=980

x + y = 13, 70 x + 80 y = 980
