x+y=2,x=15y-8

Solution

x + y = 2, x = 15 y - 8

Solution

x = \frac{11}{8}, y = \frac{5}{8}

Solution steps

[x + y = 2 x = 15 y - 8]

Substitute

x = 15 y - 8

[15 y - 8 + y = 2]

Simplify

[16 y - 8 = 2]

Isolate

y

for

16 y - 8 = 2 : y = \frac{5}{8}

For

x = 15 y - 8

Substitute

y = \frac{5}{8}

x = 15 \cdot \frac{5}{8} - 8

15 \cdot \frac{5}{8} - 8 = \frac{11}{8}

x = \frac{11}{8}

The solutions to the system of equations are:

x = \frac{11}{8}, y = \frac{5}{8}

3x+7y=27,5x+2y=16

3 x + 7 y = 27, 5 x + 2 y = 16

3y=-5x+9,x-3y=9

3 y = - 5 x + 9, x - 3 y = 9

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

2 x + y = 3, 3 x + 2 y = 8

3x+y=9,4x-5y=-7

3 x + y = 9, 4 x - 5 y = - 7
