4x+1 -3 = 26
first, +1 and -3 = -2
Move the -2 to the other side of the = sign, and it becomes +2.
+26 +(+2) = 28
Now we have 4x = 28
Divide both sides by 4 and you have 4x/4 = 28/4
Perform that division and the answer is x = 7
x = -½
many solutions
4x = -36 x = -9
It has two equal solutions of 2
-20 = -4x +6 add 20 to both sides 0 = -4x +26 4x = 26 x = 26/4 = 6.5
Just the one solution.
Two solutions and they are:- x = 0 and y = 3
It is an equation and the value of x is 4
2x + 2x + 146 + 26 = 172 4x + 172 = 172 4x = 0 x = 0
Through a process of elimination and substitution the solutions are s = 8 and x = 5
(2x + 1)(2x + 1) or (2x + 1)2 so x = -0.5
x = 2 and x = -5
