Popular >

4x+3y=-2.5,5x+2y=10

4 x + 3 y = - 2.5, 5 x + 2 y = 10

x = 5, y = - \frac{15}{2}

Solution steps

[4 x + 3 y = - 2.5 5 x + 2 y = 10]

Isolate

x

for

4 x + 3 y = - 2.5 : x = \frac{- 2.5 - 3 y}{4}

Substitute

x = \frac{- 2.5 - 3 y}{4}

[5 \cdot \frac{- 2.5 - 3 y}{4} + 2 y = 10]

Simplify

[- 3.125 - 1.75 y = 10]

Isolate

y

for

- 3.125 - 1.75 y = 10 : y = - \frac{15}{2}

For

x = \frac{- 2.5 - 3 y}{4}

Substitute

y = - \frac{15}{2}

x = \frac{- 2.5 - 3 ( - \frac{15}{2} )}{4}

\frac{- 2.5 - 3 ( - \frac{15}{2} )}{4} = 5

x = 5

The solutions to the system of equations are:

x = 5, y = - \frac{15}{2}

17 x + 10 y = 61, 5 x + 10 y = 4

2 x + y + z = 7, x - y - z = - 4, 3 x + 2 y + z = 10

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

y 13 = 1, z 13 = 10, 0.03 + j 0.09 = 3.33 - j 10

- 2 x + 3 y = 7, x + 7 y = 5
