x+y=3
y=3-2x
so
x+3-2x=3
so x=0
0+y=3
so y=3
2x = x+3 2x-x = 3 x = 3
2x=x+3=x=3
x + 3 = 2x 3 = x x cannot be 2
12!
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
2x+3=9 2x=9-3 2x=6 2x/2=6/2 X=3
2x-3 = x+5 2x-x = 8 x = 8
2x+2=x+5 x=3
x+3(x+1)=2x x + 3x + 3 = 2x 2x + 3 = 0 2x = -3 or x = -1.5
2x + 3 = 9 2x = 6 x = 3
Do you need this equation factored or? 2x+3=x+4?
