3x+32=4x-15
3x-4x=-15-32
x=-47
That sounds like: if you multiply it by 16, the result is the same as if you add 225 to it. You can write this as an equation - calling the number "x" - as follows: 16x = x + 225 Solve this equation, and you have your number.
How do you write half a number decreased by 8 is equal to the sum of the number and 14
you can write an equation: x-20=36 and move 20 to the 36 side and you do so by adding 20, so basically 20+36=56, x =5
r/2-8
write an expression for the phrase the proudut of there and a number decreased by twelve list the key words and wich opration they indicate.
w + 2.5 = 3.8
It's not an equation - there's no "is" or "equals." You can write it as a mathematical *expression*, however:140 "decreased by 20%"140 - (20/100)*140
48-n=4n-7
X = number 48 - X = 4X - 7

13-n=9. i think.

4x+x+18 = 14
125 - x.
-6 or subtract by 6 o.o
you can write an equation: x-20=36 and move 20 to the 36 side and you do so by adding 20, so basically 20+36=56, x =5
