x+3y=11,3(x-1)-5y=-68

x + 3 y = 11, 3 (x - 1) - 5 y = - 68

x = - 10, y = 7

Solution steps

[x + 3 y = 11 3 (x - 1) - 5 y = - 68]

Isolate

x

for

x + 3 y = 11 : x = 11 - 3 y

Substitute

x = 11 - 3 y

[3 (11 - 3 y - 1) - 5 y = - 68]

Simplify

[- 14 y + 30 = - 68]

Isolate

y

for

- 14 y + 30 = - 68 : y = 7

For

x = 11 - 3 y

Substitute

y = 7

x = 11 - 3 \cdot 7

Simplify

x = - 10

The solutions to the system of equations are:

x = - 10, y = 7

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

x = (x) + (x) + x, x = 4

2.5 c = 41.3, a = 3

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

a + b = 1, 4 a - b = 2
