x = 5 + 2x - 3 x = -2
y = 3 + (-x) or y = 3 - x
6x+3 where x=the number
2x-3=x+2 answer x=5

2x - 3 = x + 5 x = 8
x = 5 + 2x - 3 x = -2
y = 3 + (-x) or y = 3 - x
2x+3 where x is the unknown number
6x+3 where x=the number
The expression is: 3x+4
2 divided by 3 + x.
5=3+x
2x-3=x+2 answer x=5
Let the number in question be x. Your statement can be written as (5/6)x + 7 > -3.
The algebraic expression for "3 more than a number" can be written as x + 3, where x represents the unknown number. In this expression, the variable x is being increased by 3. This expression can be simplified further if needed, but the basic form is x + 3.
