Step 1 :Given the equation \(1-4x=25\), we are asked to determine whether each given value of \(x\) is a solution to the equation.
Step 2 :To do this, we substitute each value of \(x\) into the equation and see if the equation holds true.
Step 3 :If it does, then the value of \(x\) is a solution to the equation. If it does not, then the value of \(x\) is not a solution to the equation.
Step 4 :Substituting \(x=2\) into the equation, we get \(1-4*2=25\), which simplifies to \(-7=25\). This is not true, so \(x=2\) is not a solution to the equation.
Step 5 :Substituting \(x=-6\) into the equation, we get \(1-4*(-6)=25\), which simplifies to \(25=25\). This is true, so \(x=-6\) is a solution to the equation.
Step 6 :Substituting \(x=-3\) into the equation, we get \(1-4*(-3)=25\), which simplifies to \(13=25\). This is not true, so \(x=-3\) is not a solution to the equation.
Step 7 :Substituting \(x=5\) into the equation, we get \(1-4*5=25\), which simplifies to \(-19=25\). This is not true, so \(x=5\) is not a solution to the equation.
Step 8 :From the above, we can conclude that only \(x=-6\) is a solution to the equation \(1-4x=25\).
Step 9 :Final Answer: \(\boxed{x=-6}\)
