Answer:
x = 3
y = -5
Step-by-step explanation:
5x+2y= 5 equation 1
3х - у = 14 equation 2
using equation 2 we have:
3x - 14 = y equation 3
using equation 3 in equation 1 we have:
5x + 2(3x -14) = 5
5x + 6x -28 = 5
11x = 5+28
11x = 33
x =33/11
x = 3
using equation 3 we have:
3(3) - 14 = y
y =9-14
y = -5
Answer:
3. the numbers between -5 and 5
Step-by-step explanation:
Let set A=
and set
.
The solution set of A and B is the solution set of A∩B
The solution set of A is all the real number x which is greater than -5.
The solution set of B is all the real number x which is less than 5.
Therefore, the solution set of A∩B is all the real numbers between -5 and 5.
Hence, option (3) is correct.
