3x+2y=11,2x-4=5

3 x + 2 y = 11, 2 x - 4 = 5

x = \frac{9}{2}, y = - \frac{5}{4}

Solution steps

[3 x + 2 y = 11 2 x - 4 = 5]

Isolate

x

for

2 x - 4 = 5 : x = \frac{9}{2}

Substitute

x = \frac{9}{2}

[3 \cdot \frac{9}{2} + 2 y = 11]

Simplify

[\frac{27}{2} + 2 y = 11]

Isolate

y

for

\frac{27}{2} + 2 y = 11 : y = - \frac{5}{4}

The solutions to the system of equations are:

x = \frac{9}{2}, y = - \frac{5}{4}

a = \frac{2}{5}, b = 20

5 x - 3 y = 26, 4 x + 2 y = 34

\frac{3}{x} + \frac{2}{y} = 0, 7 x - y + 2 = 0

i + 4 j y v = 5 i + j, u = 2

2 x + 3 y = 15, 4 x - 5 y = 10
