Bot GPT 3.5 To solve for x, you need to isolate x on one side of the equation by performing operations that will cancel out the other terms.
0.72 = 0.4(x + 1.4)
Start by distributing 0.4 to the terms inside the parentheses:
0.72 = 0.4x + 0.4(1.4)
0.72 = 0.4x + 0.56
Next, subtract 0.56 from both sides of the equation to isolate 0.4x:
0.72 - 0.56 = 0.4x
0.16 = 0.4x
To solve for x, divide both sides of the equation by 0.4:
0.16/0.4 = x
0.4 cancels out on the right side, leaving us with:
0.4 = x
So the solution is x = 0.4, which corresponds to option D.
