4x-3y=9,3x-4y=5

Solution

4 x - 3 y = 9, 3 x - 4 y = 5

Solution

x = 3, y = 1

Solution steps

[4 x - 3 y = 9 3 x - 4 y = 5]

Isolate

x

for

4 x - 3 y = 9 : x = \frac{9 + 3 y}{4}

Substitute

x = \frac{9 + 3 y}{4}

[3 \cdot \frac{9 + 3 y}{4} - 4 y = 5]

Simplify

[\frac{27 - 7 y}{4} = 5]

Isolate

y

for

\frac{27 - 7 y}{4} = 5 : y = 1

For

x = \frac{9 + 3 y}{4}

Substitute

y = 1

x = \frac{9 + 3 \cdot 1}{4}

\frac{9 + 3 \cdot 1}{4} = 3

x = 3

The solutions to the system of equations are:

x = 3, y = 1

8x-5y+40=7,x-2y=0

8 x - 5 y + 40 = 7, x - 2 y = 0

7/x-(15)/y =9,*(11)/x-8/y =-17

\frac{7}{x} - \frac{15}{y} = 9, \cdot \frac{11}{x} - \frac{8}{y} = - 17

5x-2y=7,4x+3y=-2

5 x - 2 y = 7, 4 x + 3 y = - 2

3x-18y=-54,5x-4y=-40

3 x - 18 y = - 54, 5 x - 4 y = - 40

3x+2y=3,2x-2y=-8

3 x + 2 y = 3, 2 x - 2 y = - 8
