2x + w = -w
2x+3
2x+15
If: x+18 = 2x Then: x = 18
6+2x=18 x=6
It would be: 2x+4 = 19
40
2x+3
2x+15
n + 2n = 3n
If: x+18 = 2x Then: x = 18
3a-6x2
6+2x=18 x=6
It would be: 2x+4 = 19
5
It could be: 2x+16 = -24 in which case the value of x is -20
Write the following as an algebraic expression using x as the variable: The sum of a number and -8
There are two possible (and different) answers: 2x + 3y = 12 or 2*(x + 3y)= 12 The first one is (twice a number) increased by (three times another) The second is twice (a number increased by (three times another)).
