2x-y=4,-10x+5y=0

2 x - y = 4, - 10 x + 5 y = 0

No Solution

Solution steps

[2 x - y = 4 - 10 x + 5 y = 0]

Isolate

x

for

2 x - y = 4 : x = \frac{4 + y}{2}

Substitute

x = \frac{4 + y}{2}

[- 10 \cdot \frac{4 + y}{2} + 5 y = 0]

Simplify

[- 20 = 0]

- 20 = 0

is false, therefore the system of equations has no solution

No Solution

3 x + y = 5, 2 x - y = 0

a = 6, b = 4, c = 7

(6) 2 x - 2 y = y, 4 x + 3 y = - 2

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

(2 a - 1) x + 3 y - 5 = 3, x + (b - 1) y - 2 = 0
