hope it helps ;)
Step-by-step explanation:
THE ANWSER IS 2 CAUSE U HAVE TO DIVIDE
Answer:90
The answers are all real numbers where x<2 or x>2. We can use a symbol known as the union, ∪,to combine the two sets. In interval notation, we write the solution:(−∞,2)∪(2,∞). In interval form, the domain of f is (−∞,2)∪(2,∞).
A) 9(x + 4) = 27
9x + 36 = 27
9x = 27 - 36
9x = -9
x = -9 ÷ 9
x = -1
B) x/3 - 5 = 6
x/3 = 6 + 5
x/3 = 11
x = 11 × 3
x = 33
C) 15 + 3 ( x -7 ) = -30
15 + 3x - 21 = -30
3x + 15 - 21 = -30
3x - 6 = -30
3x = -30 + 6
3x = -24
x = -24 ÷ 3
x = -8
