Solve 7+3x-12x=3x+1 What does X equal?? plz help!

x = 0.5 or

Step-by-step explanation:

7+3x-12x=3x+1

  -3x      =-3x     cross out 3x

 subtract 7 on both sides

-7          =-7

divide -12 into both sides

 cross out -12 and divide -6/-12 = 0.5

To check

7+3(0.5)=8.5 - 12(0.5)=2.5

3(0.5)=1.5+1= 2.5

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
