its perfect good job honey

step-by-step explanation:

awesome job girl

simplifying

7ln(x + 2.8) = 11.2

reorder the terms:

7ln(2.8 + x) = 11.2

(2.8 * 7ln + x * 7ln) = 11.2

(19.6ln + 7lnx) = 11.2

solving

19.6ln + 7lnx = 11.2

solving for variable 'l'.

move all terms containing l to the left, all other terms to the right.

reorder the terms:

-11.2 + 19.6ln + 7lnx = 11.2 + -11.2

combine like terms: 11.2 + -11.2 = 0.0

-11.2 + 19.6ln + 7lnx = 0.0

the solution to this equation could not be determined.

step-by-step explanation:

i searched it on google but it says that the solution to this equation could not be determined but i hope that it you a little.

the answer is:

-3+7y/x

solve a system of equations when multiplication is necessary to eliminate a variable. recognize systems that have no solution or an infinite number of solutions. the elimination method for solving systems of linear equations uses the addition property of equality. you can add the same value to each side of an equation.
