If you mean: 7x-3+5x+15 = 180 then the value of x works out as 14
3+15
-10

5x + 15 = 5(x + 3)
30 + 5x = 15 + 10x 30 = 15 + 5x 15 = 5x x = 3
5x + 3 = -12 5x =-12-3 =-15 x = -3
5x = 15 so x = 15/5 = 3
No. x=3. (5x3 is 15 or 5x =15-3=12)
if you meant 5x+9=3*15 then, 5x = 36, x = 7.2 if you meant 5x+9=3x+15 then, 2x = 6, x = 3

You can factor a five out of 15 plus 5x. Therefore, 15 plus 5x factors out to 5(3+x). Hope it helps :)
5x + 3 = 18 Subtract 3 from both sides: 5x = 15 Divide by 5: x = 3.
