x-4y=2,0.8-3x+6y=-2.4

x - 4 y = 2, 0.8 - 3 x + 6 y = - 2.4

x = 0.13333 \dots, y = - 0.46666 \dots

Solution steps

[x - 4 y = 2 0.8 - 3 x + 6 y = - 2.4]

Isolate

x

for

x - 4 y = 2 : x = 2 + 4 y

Substitute

x = 2 + 4 y

[0.8 - 3 (2 + 4 y) + 6 y = - 2.4]

Simplify

[- 6 y - 5.2 = - 2.4]

Isolate

y

for

- 6 y - 5.2 = - 2.4 : y = - 0.46666 \dots

For

x = 2 + 4 y

Substitute

y = - 0.46666 \dots

x = 2 + 4 (- 0.46666 \dots)

2 + 4 (- 0.46666 \dots) = 0.13333 \dots

x = 0.13333 \dots

The solutions to the system of equations are:

x = 0.13333 \dots, y = - 0.46666 \dots

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

3 x + 4 y = 14, 5 x + 2 y = 14

g (x) = 10 x, g (x) = 15

(2 a - 1) \cdot x + 3 y = 5, 3 x + (b - 1) \cdot y = 15

x + y = 4, 2 x = 5 y
