Rnesto tried to determine the solution for the system of equations using substitution. his work is shown below. x – y = 7 3x – 2y = 8 step 1: x = y + 7 step 2: 3(y + 7) – 2y = 8 step 3: 3y + 7 – 2y = 8 step 4: y + 7 = 8 step 5: y = 1 in which step did ernesto make the first error

In the figure below, segment ac is congruent to segment ab: triangle abc with a segment joining vertex a to point d on side bc. side ab is congruent to side ac which statement is used to prove that angle abd is congruent to angle acd? segment ad bisects angle cab. triangle acd is similar to triangle abd. segment ad is congruent to segment ac. angle cab is congruent to angle cba.

Put the equation in slope intercept form by solving for y
