Answer:
x = -9
Step-by-step explanation:
6x + 6 = 3x – 21
Subtract 3x from each side
6x-3x + 6 = 3x-3x – 21
3x+6 = -21
Subtract 6 from each side
3x+6-6 = -21-6
3x = -27
Divide by 3
3x/3 = -27/3
x = -9

Answer:
B.)7√5
Step-by-step explanation:
2√5+ 5√5 = 7√5
we simply let √5 = x
therefore;
2√5+ 5√5 = 2x + 5x
2x + 5x = 7x
but x = √5
2√5+ 5√5 = 7√5
X+5−5=8−5 subtract -5 on each side
x=3
