Answer:
x=1/2
Step-by-step explanation:
6(x+3)=21
Step 1: Distribute 6 into (x+3)
6(x) = 6x
6(3) = 18
We're left with 6x+18=21
Step 2: Subtract 18 from 21
6x=21-18
6x=3
Step 3: Divide each side by 6 to isolate x
x=3/6
Step 4: Simplify
So, first you multiply 6 times x. You'll get 6x, then you multiply 6x3. You get 18. If we reverse the equation we get 21-18=3, 6x1/2=3. Therefore x=1/2
