2x-3y=10,0.4-y=10

2 x - 3 y = 10, 0.4 - y = 10

x = - 9.4, y = - 9.6

Solution steps

[2 x - 3 y = 10 0.4 - y = 10]

Isolate

y

for

0.4 - y = 10 : y = - 9.6

Substitute

y = - 9.6

[2 x - 3 (- 9.6) = 10]

Simplify

[2 x + 28.8 = 10]

Isolate

x

for

2 x + 28.8 = 10 : x = - 9.4

The solutions to the system of equations are:

x = - 9.4, y = - 9.6

3 x - 4 y = 41, 11 x + 6 y = 47

x + 3 y = 13, 3 x + y = 7

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

7 a + 5 b = 30, 2 a - 3 b = 18

4 x + 7 y = 41, 8 x - 6 y = 22
