If 2x - 13 = 5 then 2x = 5 + 13 (we have in effect added 13 to both sides of the equation in this step) 2x = 18 x = 9.
How would you solve 2x plus 1 equals 9?
2x+1 = 9 2x = 9-1 2x = 8 x = 4
What is the solution for this equation 2x--3 equals 5?
Minus a negative would give you a positive, so this could be rewritten as:2x+3 = 5Subtract three from both sides,2x = 2Divide both sides by two,x = 1
