To solve this equation, we will combine like terms and isolate the variable x.
3.5x + 8.4 = 7x - 2.1x + 3.5x + 8.4 = 4.9x + 3
Next, we will move all the terms with x to one side of the equation:
3.5x - 4.9x = 3 - 8.-1.4x = -5.4
Now, we will solve for x by dividing both sides by -1.4:
x = -5.4 / -1.x ≈ 3.857
Therefore, the solution to the equation 3.5x + 8.4 = 7x - 2.1x + 3 is x ≈ 3.857.
To solve this equation, we will combine like terms and isolate the variable x.
3.5x + 8.4 = 7x - 2.1x +
3.5x + 8.4 = 4.9x + 3
Next, we will move all the terms with x to one side of the equation:
3.5x - 4.9x = 3 - 8.
-1.4x = -5.4
Now, we will solve for x by dividing both sides by -1.4:
x = -5.4 / -1.
x ≈ 3.857
Therefore, the solution to the equation 3.5x + 8.4 = 7x - 2.1x + 3 is x ≈ 3.857.
