Final answer:
To find the values of x that make the equation true, combine like terms, isolate x on one side of the equation, and solve for x. The value of x that satisfies the equation is x = 4/7.
Step-by-step explanation:
To find the values of x that make the equation true, we need to solve the equation step by step. First, combine like terms by subtracting x from both sides and adding 4 to both sides of the equation:
2x - 4 = -5x
Next, add 5x to both sides:
2x + 5x - 4 = 0
Combine like terms:
7x - 4 = 0
Finally, add 4 to both sides and divide by 7 to solve for x:
7x = 4
x = 4/7
Therefore, the value of x that makes the equation true is x = 4/7.
