Question

2x+y=5,4x-2y=1 elimination method​

Answer 1

Answer:

2x+y=5

2x+y-y=5-y

2x=5-y

x=5-y/2

4x-2y=1

4x-2y+2y=1+2y

4x=1+2y

x=1+2y/4

Answer 2

Step-by-step explanation:

$2x + y = 5 \\ y = 5 - 2x \: \: \: \: \: \: \: \: \: \: \: \: \: eq(1)\\ \\ 4x - 2y = 1 \\ put \: the \: value \: of \: \: \: y \\ 4x - 2(5 - 2x) = 1 \\ 4x - 10 + 4x = 1 \\ 8x = 1 + 10 \\ 8x = 11 \\ x = \frac{11}{8} \\ put \: the \: value \: of \: \: \: x \: \: \: \: in \: equation \: \: 1 \\ y = 5 - 2 \times \frac{11}{8} \\ y = 5 - \frac{11}{4} \\ y = \frac{20 - 11}{4} \\ y = \frac{9}{4}$
