The solution to the equation is x = 2.5.
To solve the equation 2x + 4 = 9 for x, we'll isolate x by performing a series of algebraic operations.
The goal is to get x on one side of the equation and constants on the other.
Subtract 4 from both sides of the equation: 2x+4−4=9−4
This simplifies to: 2x=5
Divide both sides by 2 to solve for x: 2x/2 = 5/2
This yields: x= 5/2
So, the solution to the equation 2x + 4 = 9 is x= 5/2 ,
x = 2.5 .
This means that when you substitute x= 5/2 back into the original equation, the left side will equal the right side.
The value of x that satisfies the equation is 5/2, and this can be verified by substituting 5/2 back into the equation to ensure both sides are equal.
The solution is a rational number representing the point where the equation is balanced.
