Distribute negative sign: First, we need to simplify the left side of the equation by distributing the negative sign inside the parentheses.−(−4x−6.6) becomes +4x+6.6 (since −(−a)=+a for any a).So the equation now is 4x+6.6+7=−9.4.
Combine like terms: Next, we combine the like terms on the left side of the equation, which are the constant terms 6.6 and 7. 6.6+7=13.6. Now the equation is 4x+13.6=−9.4.
Subtract 13.6: To isolate the variable x, we need to subtract 13.6 from both sides of the equation.Subtracting 13.6 from both sides gives us 4x=−9.4−13.6.
Perform subtraction: Now we perform the subtraction on the right side of the equation.−9.4−13.6=−23.So the equation is now 4x=−23.
Divide by 4: To solve for x, we need to divide both sides of the equation by 4. Dividing by 4 gives us x=−423.
Simplify fraction: Finally, we simplify the fraction−423 if possible.However, −423 is already in simplest form, so x=−423.
