Question

solve for x and y 3x+y=2 ,x+y=7​

Answer 1

Answer:

3x+y=2

x+y=7

Step-by-step explanation:

x=2-y/3

2-y/3+y=7

Answer 2

Step-by-step explanation:

$3x + y = 2 \: \: \: \: \: \: \: \: \: (1)$

$x + y = 7 \: \: \: \: \: \: \: \: \: \: (2)$

Subtracting equation 1 from 2

$3x + \not{y} = 2 \\ x + \not y = 7 \\ - \: \: \: - \: \: \: - \\ 2x = \: \: - 5$

$x = \frac{ - 5}{2}$
