40
It is an equation and the value of x is 91
5
It is a linear equation in one variable, x.
Because there is no equals sign.
If: 2x = 26 Then: x = 13
40
It is an equation and the value of x is 91
5
It is a linear equation in one variable, x.
Because there is no equals sign.
Set up the equation and solve: x + 5 = -13 (next subtract 5 from each side of the equation to solve for x) x = -18
-9-2x+x = -13 -2x+x = -13+9 -x = -4 x = 4
