7x-y=5,21x-3y=10

7 x - y = 5, 21 x - 3 y = 10

No Solution

Solution steps

[7 x - y = 5 21 x - 3 y = 10]

Isolate

x

for

7 x - y = 5 : x = \frac{5 + y}{7}

Substitute

x = \frac{5 + y}{7}

[21 \cdot \frac{5 + y}{7} - 3 y = 10]

Simplify

[15 = 10]

15 = 10

is false, therefore the system of equations has no solution

No Solution

- x - 2 y = 10, 4 x + 4 y = 4

2 x - 3 y = 5, x + 4 y = 1

a = 2, b = 3, c = 4

x - y = 2, 3 x - 2 y = 1

a + b + c = 0, a - 3 b + c = 1, - 2 a - 1 c = - 1
