The triangle abc pictured below is isosceles. students were asked to find the perimeter of the triangle. jackson knew that he had to solve for x first. he also knew that because the legs of an isosceles triangle are congruent, he needed to set the measures of each of the legs equal to each other. jackson correctly set up the following equation 2x + 3 = 3x + 1 unfortunately, that is as far as jackson could go to solve the problem. explain to jackson the steps necessary to solve for x and then the rest of the steps necessary to solve for the perimeter of triangle abc.
