Answer:
The variable 8. Equation is 16 + 12x = 112.
Step-by-step explanation:
We know that she spent $16 dollars on magazines, so we can put it in the equation (16 + x= ?). We also know that the total is $112, so we can also add that (16+ x= 112). We don't know how many books she got, but we do know how much they cost (16 + 12x=112. So that makes the books the variable (X).
To find the variable we need to take out the magazines from the price. 112-16=96. Now we're left with 12x=96. Now all we have to do is divide 96 by 12, which equals 8.
Sorry everything is so long, I tried to make it short as possible
Remove the unnecessary parentheses so it would be -1.3x - 4.5 + 2.1x -3.6. combine the like terms -1.3x & + 2.1x & it becomes 0.8x & then you combine -4.5 -3.6 & it becomes -8.1 so your answer is 0.8x-8.1 !! let me know if that was right
