8x+y=-16,-3x+y=-5

Solution

8 x + y = - 16, - 3 x + y = - 5

Solution

x = - 1, y = - 8

Solution steps

[8 x + y = - 16 - 3 x + y = - 5]

Isolate

x

for

8 x + y = - 16 : x = \frac{- 16 - y}{8}

Substitute

x = \frac{- 16 - y}{8}

[- 3 \cdot \frac{- 16 - y}{8} + y = - 5]

Simplify

[\frac{48 + 11 y}{8} = - 5]

Isolate

y

for

\frac{48 + 11 y}{8} = - 5 : y = - 8

For

x = \frac{- 16 - y}{8}

Substitute

y = - 8

x = \frac{- 16 - ( - 8 )}{8}

\frac{- 16 - ( - 8 )}{8} = - 1

x = - 1

The solutions to the system of equations are:

x = - 1, y = - 8

x+3y=17,x+2y=12

x + 3 y = 17, x + 2 y = 12

10x-(4a+4b)x=5,a+b=13

10 x - (4 a + 4 b) x = 5, a + b = 13

4x-5y-11z=1,2x-3y+z=1,2x+3y-5z=2

4 x - 5 y - 11 z = 1, 2 x - 3 y + z = 1, 2 x + 3 y - 5 z = 2

x + y = 4, x = 2

3x-5y=0, x/5+y/3 =2

3 x - 5 y = 0, \frac{x}{5} + \frac{y}{3} = 2
