5x + 3 = 2x + 15 x =?

5x+3=2x+15=
-2x-3=-2x-3=
3x=12
12/3=4
x=4

5x + 3 = 2 x + 15
3 x = 12
x = 4

x= 4

4

5x + 3 = 2x + 15

5x - 2x = 15 - 3

3x = 12

........12
x = ------------
.........3

...= 4

Answer:

x = 4

5x + 3 = 2x + 15
5x-2x = 15-3
3x=12
x=4

X=4

5x+3=2x+15
-3 -3 = 5x=2x+12
-2x -2x 3x=12

Divide by 3
x=4

5x + 3 = 2x + 15
5x - 2x = -3 + 15
3x = 12
x = 12/3
x = 4

4

5x + 3 = 2x + 15
subtract 2x from both sides:
5x + 3 - 2x = 2x + 15 - 2x => 3x +3 = 15
subtract 3 from both sides:
3x + 3 - 3 = 15 - 3 => 3x = 12
divide both sides by 3:
3x/3 = 12/3 => x = 4
