Since there are ten of them I will give 45 points (I only have 90) I'm giving you all my points for this guys. Please give me a real answer.
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
