Solve the equation 2x - 0.4 = 1 + 1.8x (point) 07 017 07
To solve the equation 2x - 0.4 = 1 + 1.8x, you first want to isolate the x variable on one side of the equation.
Subtract 1.8x from both sides of the equation:
2x - 1.8x - 0.4 = 1 + 1.8x - 1.8x
0.2x - 0.4 = 1
Next, add 0.4 to both sides of the equation:
0.2x - 0.4 + 0.4 = 1 + 0.4
0.2x = 1.4
To solve for x, divide both sides by 0.2:
x = 1.4 / 0.2
x = 7
Therefore, the solution to the equation 2x - 0.4 = 1 + 1.8x is x = 7.
