How do you solve seven less than three times a number is a most 9?
3x - 7 ≤ 9 "Seven less than" means that you subtract seven from the answer. "Three times a number" means that you multiply it. "At most" means that this is the greatest number that it can be, which is, in this case, 9. To solve this, you apply the principle rules of algebra to determine x. 3x ≤ 9 + 7 3x ≤ 16 x ≤ 16/3
How do you solve each system by the addition method?
solve system equation using addition method 3x-y=9 2x+y=6
How do you solve for x when it's a fraction?
you multiply by its denominator to each side. Example: 3x/5=9 now multiply by 5 to each side 3x/5 times 5 is 3x and 9 times 5 is 45 so you get 3x=45 now divide by 3 to each side and you get x=15
3x minus y equals 9 solve for y?
3x-y=9 y=3x-9

How do you solve for y 3x-y equals 12?
-9
How do you solve 3x equals 9?
3x=9 means 3 times a number is equal to 9. Divide both sides by 3. 1) 3x/3=9/3 Dividing 3x by 3 cancels the 3 from the x. 2) 3x/3=9/3 Cleaning up the equation looks like this: 3) x=9/3 Solve the right side. 4) x=3
Solve for x. 9 equals 12 - 3x?
x . 9 =12-3x9x =12-3x9x+3x=1212x =12x =1
Solve 24 equals 3x plus 9?
24 = 3x + 9 -9 -9 Subtract 9 from each side15 = 3x/3 /3 Divide 3 from each side5 = x You are left with five equals X
