Johan found that the equation -2|8-x|-6=-12 had two possible solutions x=5 and x=-11.which explains whether his solutions are correct? a he i correct both solutions satisfy the equation b he is not correct he made a sign error c he is not correct because there are no solutions d he is not correct because there is only one solution x=5

we have

Find the two possible solutions

Step 1

Find the first solution

we know that

the first solution is for the term positive

therefore

the first solution is

Step 2

Find the second solution

we know that

the second solution is for the term negative

therefore

the second solution is

therefore

the answer is the option

B he is not correct he made a sign error

this is answer of 144 cubic meters

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
