-3(3x+15)-(10+x)=35What is the answer to this ques5
2 answers:
Solve for x: -3 (3 x + 15) - (x + 10) = 35 -3 (3 x + 15) = -9 x - 45: -9 x - 45 - (x + 10) = 35 -(x + 10) = -x - 10: -9 x + -x - 10 - 45 = 35 Grouping like terms, -x - 9 x - 45 - 10 = (-9 x - x) + (-45 - 10): (-9 x - x) + (-45 - 10) = 35 -9 x - x = -10 x: -10 x + (-45 - 10) = 35 -45 - 10 = -55: -55 - 10 x = 35 Add 55 to both sides: (55 - 55) - 10 x = 55 + 35 55 - 55 = 0: -10 x = 35 + 55 35 + 55 = 90: -10 x = 90 Divide both sides of -10 x = 90 by -10: (-10 x)/(-10) = 90/(-10) (-10)/(-10) = 1: x = 90/(-10) The gcd of 90 and -10 is 10, so 90/(-10) = (10×9)/(10 (-1)) = 10/10×9/(-1) = 9/(-1): x = 9/(-1) Multiply numerator and denominator of 9/(-1) by -1:Answer: x = -9
Answer is : X = -9 I did the math and thats what I got

4.5
Step-by-step explanation:
One half is equal to 0.5, you then multiply 0.5 by 9 because 90 divided by 10 (every 10 pounds) is 9. Your answer is 4.5.
