x + 5x + 6x = 12x. There are 3 terms.
If the arithmetic mean is 8 then 12x = 3 x 8 = 24 : So, x = 24 ÷ 12 = 2.
If you mean: 5x = 10 then the value of x is 2
If you mean 5x = 140 then the value of x is 140/5 = 28
There is no definitive answer unless you are given the value of x
if you mean 5x -2y = 10 then y = 2.5x -5
The value of x is: x=7/8. Work: 5x-3=4-3x +3 +3 ________ 5x=7-3x +3x +3x ________ 8x=7 /8 /8 ________ x=7/8
If you mean: 7x-2 = 5x+16 then the value of x works out as 9
If you mean 5x+2 = 12 then 5x = 10 and the value of x is 2
If you mean: 7x-2 = 5x+16 then the value of x works out as 9
If you mean 5x+4x = 54 then the value of x is 6
x = 1
If you mean: 7x-2 = 5x+16 then the value of x works out as 9
If you mean: 5x = 10 then the value of x is 2
5x+3y is an algebraic expression in two terms
If you mean: 3+5x+7 = 70 then the value of x is 12
If you mean: 3(x-6) = 5x-7 then the value of x works out as -5.5
If you mean: 7x-3+5x+15 = 180 then the value of x works out as 14
NO!!! Because it is not equated to any value. However if you mean y^(2) - 5x = 0 Then y^(2) = 5x is NOT a linear equation. It is a parabola lying on its side.
