Hideki found the solution for the equation below to be r = 66.6(5 + r) = 96 What mistake did Hideki make in solving the equation? What is the correct solution? A. He did not distribute 6 to r; r = 11.
B. He did not divide both sides by 6; r = 16.
C. He did not multiply both sides by 6; r = 571.
D. He did not subtract 5 from both sides; r = 15.

See for the answer below:

Step-by-step explanation:

The answer is A.

goog may be able to you find that answer

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
