There is no operator visible between 7 and x.
<<>> assuming that you mean y=7x in other words y equals 7 times x, that is an equation, no problem, but when you have two unknowns you have to have two equations to solve it and they have to be independent.
Example: y=7x, y=6+x are two inpdependent equations and it's possible to replace the first equation in the second, which gives 7x=6+x, in other words 6x=6 or x=1, and then either equation says that y=7.

Solve for x when y equals 3x 7?
that's impossible
How do you solve y equals -x - 5 if x equals -2?
7
Solve using elimination x plus y equals 8 and x minus y equals 6?
X + y = 8 x - y = 6 add equations to eliminate y 2x = 14 x = 7 substitute 7 + y = 8 y = 1
X plus y plus z equals 9 and x plus 2y plus 3z equals 23 and x plus 5y-3Z equals -7 solve for x and y and z?
Can you help with this equation? Thanks. Solve for x and y and z for the following. x plus y plus z equals 9 x plus 2y plus 3z equals 23 x plus 5y plus -3z equals -7
What is x-y equals 7 in slope form?
y = x - 7 or, y = 1*x - 7 so that the slope is 1.
