3a-2b=0,-19-9b=-65

3 a - 2 b = 0, - 19 - 9 b = - 65

a = \frac{92}{27}, b = \frac{46}{9}

Solution steps

[3 a - 2 b = 0 - 19 - 9 b = - 65]

Isolate

b

for

- 19 - 9 b = - 65 : b = \frac{46}{9}

Substitute

b = \frac{46}{9}

[3 a - 2 \cdot \frac{46}{9} = 0]

Simplify

[3 a - \frac{92}{9} = 0]

Isolate

a

for

3 a - \frac{92}{9} = 0 : a = \frac{92}{27}

The solutions to the system of equations are:

a = \frac{92}{27}, b = \frac{46}{9}

2 x + y = 5, 2 x - y = 8

x + y + z = 11, x - y + 3 z = 13, 2 x + 2 y - z = 7

11 x - 13 y = 53, 7 x + 9 y = - 139

4 x + 3 y = 18, 5 x + 6 y = 27

\frac{x}{2} + y = 0, x - \frac{y}{3} = \frac{1}{2}
