<h3>20 subtracted from three times a number is 6 more than the number. Then the number is 13</h3>
<em><u>Solution:</u></em>
<em><u>Given statement is:</u></em>
20 subtracted from three times a number is 6 more than the number
We can translate the sentence into algebraic expression
Let "a" be the unknown number
Then,
20 subtracted from three times "a" is 6 more than "a"
Which means,
3a - 20 = 6 + a
3a - a = 6 + 20
2a = 26
Divide both sides by 2
a = 13
Thus the number is 13
Answer:
x= -10
Step-by-step explanation:
4.5(8 - x) + 36 = 102 - 2.5(3x + 24)
4.5(8) - 4.5(x) + 36 = 102 - 2.5(3x) -2.5(24)
36 - 4.5x + 36 = 102 - 7.5x - 60
72 - 4.5x = 102 - 7.5x - 60
-4.5x = 102 - 7.5x - 60 - 72
-4.5x + 7.5x = -30
3x = -30
x = -30/3
x = -10
