You can use the ad that is faster and show you the steps is called
3x = -6y + 6 becomes x = -2y + 2 and then you substitute in 5( -2y + 2) + 4y = -14
-10y + 10 + 4y = -14
-6y = -24
6y = 24
y = 4
And then you put y in x = -2(4) + 2 to find x
X = -8 + 2 = -6
x = -6
Then you try in both
5(-6) + 4(4) = - 14 -> -30 + 16 is -14 ✔️
3(-6) + 6(4) = 6 -> -18 + 24 is 6 ✔️
Answer:
Step-by-step explanation:
6< 3x + 9
-3x < 9-6
-3x < 3 .( -1 )
3x > 3
x > 3/3
x > 3
3x + 9 ≤ 18
3x ≤ 18-9
3x ≤ 9
x ≤ 9/3
x ≤ 3
S = {XeIR/ 3 > x ≤ 3 }
Not sure if the solution looks like this
If you substitute the values for x and y you will find that D. is the only function which satisfies the given values.
