x can be anything, if you don't have it in an equation form, can an be an infinite amount of solutions
19 (7 + 12 = 4x - 3x)
Yes
Let's call this number x. 4x+7=35 4x=28 x=7
You need to organise your question properly. 3x+2y=4 4x + 3y= 7? Is 4 4x = 44x or 4-4x or 4+4x How can there be 2 equal signs in 1 equation?
The expression "4x plus 7" is equivalent to the algebraic expression (4x + 7). This represents a linear equation where (4x) indicates that the variable (x) is multiplied by 4, and then 7 is added to that product. It can also be used in various mathematical contexts, such as solving for (x) when set equal to a specific value.
If 4x + 7 = 3... then x must equal -1
19 (7 + 12 = 4x - 3x)

Yes.
8x + 15
3x+7=4x 7=4x-3x 7=x
If: 5x = 4x+7 Then: 5x-4x = 7 And: x = 7
4x + 7 = 6x -7 14=2x so x = 7 (plus a negative # is simply - that number)
4x+7=9x+7 -5x=0 x=0
