linear equations: show your work to solve each equation then answer the questions.

#1

7(y + 3) = 5y + 8

how many solutions does the above equation have? (one solution, infinite solutions, no solution)

#2

10 + 6x = 2(5 + 3x)

how many solutions does the above equation have? (one solution, infinite solutions, no solution)

#3

3x + 5 - x = 2x + 7

how many solutions does the above equation have? (one solution, infinite solutions, no solution)

#4
