I'm newbie here
Step-by-step explanation:
Elimination Method.
4x + 6/y = 15 → step 1
6x - 8/y = 14 → step 2
so,
4x + 6/y = 15 |×6|
6x - 8/y = 14 |×4|
24x + 6/y(6) = 90
24x - 8/y(4) = 56
24x + 36/y = 90
24x - 32/y = 56
____________ _
68/y = 34
68 = 34y
34y = 68
y = 2
subsitution y = 2 to..
4x + 6/y = 15
4x + 6/2 = 15
4x + 3 = 15
4x = 12
x = 3
So, for x is 3, and for y is 2

divided 3 and 31.50 and then add 31.50 + 10.50 = 42.00
Answer:
The answer to your question is (-2, ∞)
Step-by-step explanation:
Data
2(3x - 1) > 4x - 6
Process
-Expand
6x - 2 > 4x - 6
-Subtract 4x in both sides
6x - 4x - 2 > 4x - 6 - 4x
-Simplify
2x -2 > -6
-Add 2 in both sides
2x - 2 + 2 > -6 + 2
-Simplify
2x > -4
-Divide by 2 both sides
2x/2 > -4/2
-Simplify
x > -2
-Result
All the numbers higher than -2
