-5x+2y=9,y=7x

Solution

- 5 x + 2 y = 9, y = 7 x

Solution

x = 1, y = 7

Solution steps

[- 5 x + 2 y = 9 y = 7 x]

Substitute

y = 7 x

[- 5 x + 2 \cdot 7 x = 9]

Simplify

[9 x = 9]

Isolate

x

for

9 x = 9 : x = 1

For

y = 7 x

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

x - 5 y = 6 x - 8, y = 3

5x+3y+17=4,x+y+15=0

5 x + 3 y + 17 = 4, x + y + 15 = 0

5 x - 8 x = 5, x = 80 x

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