The sum of five times a number and 6 more than the number is the same as the difference between -18 and twice the number. What i
s the number?
2 answers:
5x + (6+x) = -18 - x
6x + 6 = -18 - x
6x + x = -18 - 6
7x = -24
x = -24/7
N = -3
5n + n + 6 = -18 - 2n
6n + 6 = -18 - 2n
-6 to both sides
6n = -24 - 2n
+2n to both sides
8n = -24
divide 8 to both sides
n = -3

Well, 1x5=5 and 2x5=10 so 3x5=15
-x + y = 4
2x+3y= 2
-2x + 2y = 8
2x + 3y = 2
5y = 10
y= 2
-x + 2 = 4
-x = 2
x = -2
All except 0. The inequality is saying that x must be less than or equal to 3 which all answers except 0 are.
