Q. If −18=6−12x, what is the value of 1−2x ?Choose 1 answer:(A) −4(B) −3(C) 2(D) 3
Solve for x: First, we need to solve for x in the equation -18 = 6 - 12x").\(\newline\$-18 = 6 - 12x")\(\newline\)Subtract 6 from both sides to isolate the terms with x.\(\newline\)\$-18 - 6 = 6 - 6 - 12x")\(\newline\)\$-24 = -12x")\(\newline\)Now, divide both sides by \$-12\) to solve for x.\(\newline\)\(-24 / -12 = (-12x) / -12")\(\newline\)\$x = 2\)
Substitute \(x\) into expression: Now that we have the value of \(x\), we can substitute it into the expression \(1 - 2x\) to find its value.\(\newline\)\(1 - 2x = 1 - 2(2)\)\(\newline\)Calculate the multiplication.\(\newline\)\(1 - 2x = 1 - 4\)\(\newline\)Now, subtract \(4\) from \(1\).\(\newline\)\(1 - 4 = -3\)
