2x-1 =13 please help me to understand how to work this one it is due tonight thank you
2x-1=13
2x=13+1
2x=14
x=14/2
x=7
thank you john I really appericate your help.
To solve the equation 2x - 1 = 13, let's go step by step:
Step 1: Isolate the variable term.
To get rid of the constant term (-1) on the left side of the equation, we need to add 1 to both sides:
2x - 1 + 1 = 13 + 1
Simplifying the equation gives:
2x = 14
Step 2: Solve for the variable.
To isolate x, we need to get rid of the coefficient 2. To do this, we can divide both sides of the equation by 2:
(2/2)x = 14/2
Simplifying further:
x = 7
So, the solution to the equation 2x - 1 = 13 is x = 7.
To check our answer, we can substitute x = 7 back into the original equation:
2(7) - 1 = 14 - 1 = 13
This confirms that x = 7 is indeed the correct solution.
