It depends on what the angle is and what other information is given.
If measure angle 3 = x2 + 4x and measure angle 5 = 3x + 72, find the possible measures of angle 3 and angle 5
The value of x in the equation -10+4x = 50 is 15
16x
The value of x in the equation -2 x plus 3 4x-3 is 3.
If you mean 5x+4x = 54 then the value of x is 6
The value of x is 2
15
If you mean: -3-10x = 25+4x then the value of x works out as -2
If you mean 49+6 = 4x-7 then the value of x is 15.5
27
It is an equation and the value of x is 4
It is an equation and the value of x is 6
