y=2(x+10),3x+2y=19

y = 2 (x + 10), 3 x + 2 y = 19

x = - 3, y = 14

Solution steps

[y = 2 (x + 10) 3 x + 2 y = 19]

Substitute

y = 2 (x + 10)

[3 x + 2 \cdot 2 (x + 10) = 19]

Simplify

[7 x + 40 = 19]

Isolate

x

for

7 x + 40 = 19 : x = - 3

For

y = 2 (x + 10)

Substitute

x = - 3

y = 2 (- 3 + 10)

Simplify

y = 14

The solutions to the system of equations are:

x = - 3, y = 14

- 4 x + y = 20, 6 x - 9 y = 0

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

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
