In the following questions, determine whether the equation has a solution, no solution, or an infinite number of solutions. Specify which, and then solve the equation if there is a solution.

7(x-5)=x+13

-6x=-5(x-1)-x

-4(x-2)=-2(x-17/2)

3-4x+5=2(8-2x)

2x+3=+2x

2x+3=2x+5

3x+9=2.5x+14

7(x-4)=4x+5

5x-20=-7x-20

3(2x+1)-4x=2x+3
