Question

answer this equation either by elimination or substitution
3x₋2y=8
2x₋2y=4

Answer 1

Answer:

x=4

y=2

Step-by-step explanation:

by subtracting both equation we got the value of x and by putting in any one equation we got the value of y

Answer 2

${ \underline {\underline {\star \: {given}}}}$

$3x - 2y = 8. - - - - - - - (1) \\ \\ 2x - 2y = 4. - - - - - - - (2)$

Now,

Subtracted equation (1) - (2)____________

$3x - 2y = 8. \\ \\ 2x - 2y = 4 \\ \\ - - - - - - - - - - \\ \\ x \: \: \: \: \: \: \: \: \: \: \: \: = 4.$

Putting the value of x = 4 in equation (1)______

$3x - 2y = 8. \\ \\ 3(4) - 2y = 8. \\ \\ 12 - 2y = 8. \\ \\ - 2y = - 4. \\ \\ y = 2$

Hence,
