2x-5y=-17,2x+3y=23

Solution

2 x - 5 y = - 17, 2 x + 3 y = 23

Solution

x = 4, y = 5

Solution steps

[2 x - 5 y = - 17 2 x + 3 y = 23]

Isolate

x

for

2 x - 5 y = - 17 : x = \frac{- 17 + 5 y}{2}

Substitute

x = \frac{- 17 + 5 y}{2}

[2 \cdot \frac{- 17 + 5 y}{2} + 3 y = 23]

Simplify

[- 17 + 8 y = 23]

Isolate

y

for

- 17 + 8 y = 23 : y = 5

For

x = \frac{- 17 + 5 y}{2}

Substitute

y = 5

x = \frac{- 17 + 5 \cdot 5}{2}

\frac{- 17 + 5 \cdot 5}{2} = 4

x = 4

The solutions to the system of equations are:

x = 4, y = 5

v (t) = 42, 0 \cdot 2^{0.2} \cdot t = 67200

2x-5=3,x+2y=3y+13

2 x - 5 = 3, x + 2 y = 3 y + 13

x + y = 1, 5 x - 4 y = - 1

x + y = 1, 0.1 x - y = 1

x-y=-1,-x-3y=-11

x - y = - 1, - x - 3 y = - 11
