Remove all the brackets
3(7 + 2x) + 3 = 3(5 + x) − 9(x + 1)
21 + 6x + 3 = 15 + 3x - 9x - 9 Collect like terms.
24 + 6x = 6 - 6x Add 6x to both sides.
24 + 6x + 6x = 6 Subtract 24 from both sides
12x = 6 - 24
12x = - 18 Divide by 12
x = - 18 /12
x = - 1.5
Check
3(7 + 2*(-1.5)) + 3 = ? 3(5 + -(1.5) - 9(-1.5 + 1)
3(7 - 3) + 3 =? 3(3.5) - 9*(-1/2)
3*4 + 3 =? 10.5 + 4.5
12 + 3 =? 15 And it checks.

Answer:
OK wait for a min OK plz ok
3 to fourth power=3^4
3 to ninth power =3^9
Now,
3 to fourth power times to the ninth power=3^4*3^9
the basis same so the powers will add:
3^(4+9)=3^13=1594323
Answer:
50 laps
Step-by-step explanation:
20+1.25x+15+2.5x+40+1.5x+25+1.75x=450
7x+100=450
7x+200-200=450-100
7x=350
7x/7=350/7
x=50
