X=5+y
Substitute the value of x in second equation
28x – 9y= -12
28 (5+y)-9y =-12
140 +28y -9y =-12
140 +19y= -12
19y = - 152
y= -8
Now let's find the value of x using y
x= 5+y
x= 5 + (-8)
= -3
So,
x= -3
y=-8

Answer:
Has not solution.
Step-by-step explanation:
14x÷2 = 6(x - 0)
14x÷2 = 6*x + 6*-0
14x÷2 = 6x - 0
14x = 2*6x
14x ≠ 12x
then:
This equation has not solution.
Answer:
The answer is: 3 1/3.
Step-by-step explanation:
To find this answer, divide 5/4 by 3/8.
(5/4) / (3/8) = 5/4 * 8/3 = 40/12 = 10/3 or 3 and 1/3.
Proof:
10/3 * 3/8 = 30/24 = 5/4
