x+5y=-2,3x-4y=-25

Solution

x + 5 y = - 2, 3 x - 4 y = - 25

Solution

x = - 7, y = 1

Solution steps

[x + 5 y = - 2 3 x - 4 y = - 25]

Isolate

x

for

x + 5 y = - 2 : x = - 2 - 5 y

Substitute

x = - 2 - 5 y

[3 (- 2 - 5 y) - 4 y = - 25]

Simplify

[- 6 - 19 y = - 25]

Isolate

y

for

- 6 - 19 y = - 25 : y = 1

For

x = - 2 - 5 y

Substitute

y = 1

x = - 2 - 5 \cdot 1

Simplify

x = - 7

The solutions to the system of equations are:

x = - 7, y = 1

10r-9a+6=7,r-6a-3=0

10 r - 9 a + 6 = 7, r - 6 a - 3 = 0

z = 5 - 2 i, w (z) = 6 i

x/2+y/3 = 1/2 ,x+y/2 = 3/2

\frac{x}{2} + \frac{y}{3} = \frac{1}{2}, x + \frac{y}{2} = \frac{3}{2}

x-2y+3z=9,-x+3y-z=17

x - 2 y + 3 z = 9, - x + 3 y - z = 17

2x-3y=-5,5x+3y=19

2 x - 3 y = - 5, 5 x + 3 y = 19
