The answer will be x = -4
Seven less than twice x is 15. What is x?
Translation:[tex]\tt{7 - 2x = 15}[/tex]
Solution:
[tex]\tt{7 - 2x = 15}[/tex]
[tex]\tt{7 - 7 - 2x = 15 - 7}[/tex]
[tex]\tt{- 2x = 15 - 7}[/tex]
[tex]\tt{- 2x = 8}[/tex]
[tex]\tt{\frac{- 2x} {-2}= \frac{8}{-2}}[/tex]
[tex]\boxed{\tt{x = -4}}[/tex]
Answer:
x = 11
Solution:
2x - 7 = 15
2x = 7 + 15
2x / 2= 22 / 2
x = 11
