Answer:
X = -3
Step-by-step explanation:
Multiply both sides by 3
3x 1/3(3) = -3(3)
3x/3 = -9/3
divide both sides by 3 to isolate x
x = -3
I am only guessing that you mean:
(n-2)/-3<7 if so, multiply both sides by -3 (and reverse the direction of the inequality sign because of negative mulitplication!)
n-2>-21 add 2 to both sides
n>-19
Answer:
12
Step-by-step explanation:
3x + 7 = 5x - 17
5x - 3x = 7 + 17
2x = 24
x = 12
