What is 2x + 5 = 15 - (-49) x 5

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
