Answer:
x= -4
Step-by-step explanation:
1. Expand the brackets (multiply everything inside by the number outside):
5x + 15= 2x + 3
2. Move all of the x terms to one side and all of the number terms to the other:
Subtract 2x from both sides
5x-2x + 15= 2x-2x + 3
3x + 15= 3
Subtract 15 from both sides
3x + 15- 15= 3 - 15
3x= -12
3. Solve for x:
x= -12/3
x= -4
