Answer:
X=3,y=-2
Step-by-step explanation:
This is a simultaneous equation question and we will have to solve using substitution method
So let's solve
y=-2x+4...(1)
y=-2....(2)
Let's substitute (2) into (1)
-2=-2x+4
Substrate 4 from both sides
-6=-2x
Divide both sides by-2
x=3
Substitute the value of x in (1)
y=-2(3)+4
y=-6+4
y=-2
Therefore x is 3,y is -2
Answer:
B
7 less than 3 times a number (X) is (3x-7), and then the sum of these two numbers means we have (3x-7)+X, and then we know this equals 109, leaving us with:
(3x-7)+x = 109
6y - 8 ≤ 10 Add 8 to both sides
6y ≤ 18 Divide both sides by 6
y ≤ 3
Y is less than or equal to 3.
Answer:
<
Step-by-step explanation:
the inverse of -18 is +18. +18 is less than 19
