Q. 3(2n−2)−1=49Given the equation, what is the value of 2n−2 ?Choose 1 answer:(A) 125(B) 1213(C) 47(D) 413
Simplify Left Side: First, we need to simplify the left side of the equation by distributing the 3 into the parentheses.3(2n−2)−1=3×2n−3×2−1=6n−6−1=6n−7
Set Equal and Solve: Now, we set the simplified expression equal to the right side of the equation and solve for n.6n−7=49
Isolate n: Next, we add 7 to both sides of the equation to isolate the term with n on one side.6n−7+7=49+76n=49+4286n=437
Find Value of n: To find the value of n, we divide both sides of the equation by 6.n=437/6n=437×61n=2437
Find Value of 2n−2: Now that we have the value of n, we can find the value of 2n−2.2n−2=2×2437−2=2474−2448=2426=1213
