1/2(k-5)=3
Well, since you did nt read the chapter on parentheses I will have to guess a couple of possibilities.
(1/2)(k-5) = 3
k - 5 = 6
k = 11
or maybe
1/[2(k-5)] = 3
1 = 6(k-5)
1 = 6 k - 30
6 k = 31
k = 31/6
( 1 / 2 ) ( k - 5 ) = 3 Multiply both sides by 2
k - 5 = 6 Add 5 to both sides
k - 5 + 5 = 6 + 5
k = 11
Proof :
( 1 / 2 ) ( k - 5 ) = ( 1 / 2 ) ( 11 - 5 ) = 6 / 2 = 3
To solve the equation 1/2(k - 5) = 3, we need to isolate the variable k. Here's how you can do it step by step:
Step 1: Distribute the 1/2 to the terms inside the parentheses:
(k/2) - (5/2) = 3
Step 2: Simplify the equation by combining like terms:
k/2 - 5/2 = 3
Step 3: To get rid of the fraction, multiply the entire equation by 2 (this will cancel out the denominators):
2*(k/2) - 2*(5/2) = 2*3
k - 5 = 6
Step 4: Finally, isolate the k variable by adding 5 to both sides of the equation:
k - 5 + 5 = 6 + 5
k = 11
Therefore, the solution to the equation 1/2(k - 5) = 3 is k = 11.
