4.7 is the approximate answer
Ответ:
x = 1
y = 2
Step-by-step explanation:
3y + x = 7 first equation
-2y + 4x = 0 second equation
multiplying by -4 the first equatión
-4(3y + x = 7)
-4*3y -4*x = -4*7
-12y -4x = - 28
and sum the second equation:
-12y - 4x = -28
- 2y - 4x = 0
-14y - 0 = -28
-14y = -28
y = -28/-14
y = 2
from the first equation:
3y + x = 7
3*2 + x = 7
6 + x = 7
x = 7 - 6
x = 1
Check:
from the second equation:
4x - 2y = 0
4*1 - 2*2 = 0
4 - 4 = 0
