7x+8y=29,5x+11y=26

Solution

7 x + 8 y = 29, 5 x + 11 y = 26

Solution

x = 3, y = 1

Solution steps

[7 x + 8 y = 29 5 x + 11 y = 26]

Isolate

x

for

7 x + 8 y = 29 : x = \frac{29 - 8 y}{7}

Substitute

x = \frac{29 - 8 y}{7}

[5 \cdot \frac{29 - 8 y}{7} + 11 y = 26]

Simplify

[\frac{145 + 37 y}{7} = 26]

Isolate

y

for

\frac{145 + 37 y}{7} = 26 : y = 1

For

x = \frac{29 - 8 y}{7}

Substitute

y = 1

x = \frac{29 - 8 \cdot 1}{7}

\frac{29 - 8 \cdot 1}{7} = 3

x = 3

The solutions to the system of equations are:

x = 3, y = 1

3 (3 x + 5) = 6 x - y + 9, 12 x + 5 y = - 32

4x+3y=1,5x+3y=8

4 x + 3 y = 1, 5 x + 3 y = 8

5x+3y=9,2x-3y=12

5 x + 3 y = 9, 2 x - 3 y = 12

3x+2y+z=2,4x+2y+2z=8,x-y+z=4

3 x + 2 y + z = 2, 4 x + 2 y + 2 z = 8, x - y + z = 4

-4x+6y=21,5x-6y=9

- 4 x + 6 y = 21, 5 x - 6 y = 9
