So, you do - 49 * 5 first because multiplication is before addition, which is - 245.
15 - (-245) turns into addition, so the right side of the equation is 260.
Move the 5 over. 260-5 = 255
2x = 255, so x = 255/2 or 127.5

2x + 5 = 15 - (-49) x 5
combine like terms
2x + 5 = 320
subtract 5 from each side
2x = 315
divide by 2 on each side
x = 157.5
