Step 1:I'll solve this step-by-step using the specified LaTeX formatting guidelines:
Step 2:: Isolate the variable term
0.7x = -2.1
• Start by adding 1.4 to both sides of the equation to move the constant term
Step 3:: Solve for x by dividing both sides by 0.7
\frac{0.7x}{0.7} = \frac{-2.1}{0.7}
x = - 3
Step 4:: Verify the solution
-2.1 - 1.4 = -3.5 ✓
0.7(- 3) - 1.4 = - 2.1 - 1.4
Final Answer
The solution is option B, which is - 3.
