8x+5y=9,3x+2y=4

Solution

8 x + 5 y = 9, 3 x + 2 y = 4

Solution

x = - 2, y = 5

Solution steps

[8 x + 5 y = 9 3 x + 2 y = 4]

Isolate

x

for

8 x + 5 y = 9 : x = \frac{9 - 5 y}{8}

Substitute

x = \frac{9 - 5 y}{8}

[3 \cdot \frac{9 - 5 y}{8} + 2 y = 4]

Simplify

[\frac{27 + y}{8} = 4]

Isolate

y

for

\frac{27 + y}{8} = 4 : y = 5

For

x = \frac{9 - 5 y}{8}

Substitute

y = 5

x = \frac{9 - 5 \cdot 5}{8}

\frac{9 - 5 \cdot 5}{8} = - 2

x = - 2

The solutions to the system of equations are:

x = - 2, y = 5

3x+2y=4,9x+6y=12

3 x + 2 y = 4, 9 x + 6 y = 12

4x-y=12,2x+3y=-5

4 x - y = 12, 2 x + 3 y = - 5

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

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

-9x-((9y))/7 =15,-3x+2/9*y=7

- 9 x - \frac{( 9 y )}{7} = 15, - 3 x + \frac{2}{9} \cdot y = 7

3(x+y)=2,x-1x+y=-5

3 (x + y) = 2, x - 1 x + y = - 5
