2x = x+3 2x-x = 3 x = 3

2x=x+3=x=3

x + 3 = 2x 3 = x x cannot be 2

2x + 3 = x 2x + 3 - 3 = x - 3 2x = x - 3 2x - x = x - 3 - x x = -3

2x = 4x + 3 -2x = 3 x = -3 / 2

x+3(x+1)=2x x + 3x + 3 = 2x 2x + 3 = 0 2x = -3 or x = -1.5

2x-3 = x+5 2x-x = 8 x = 8

2x+2=x+5 x=3

the converse of this conditional is true

Do you need this equation factored or? 2x+3=x+4?

2x-3=x+2 2x-x=2+3 x=5
