Answer:
x=-32/11
Step-by-step explanation:
Let's solve your equation step-by-step.
1/(x+3)=11
(1/n=reciprocal of n)
Step 1: Multiply both sides by x+3.
1=11x+33
11x+33=1(Flip the equation)
11x+33−33=1−33(Subtract 33 from both sides)
11x=−32
11x/11=−32/11
(Divide both sides by 11)
x=−32/11
Check answers. (Plug them in to make sure they work.)
x=−32/11
(Works in original equation)
