Answer:
x=-6
Step-by-step explanation:
Use Substitution
so 5-2x=-4x-7
I'ma move that -4x to the other side by making it a positive
5+2x=-7
than I'ma move that 5 to the other side by making it a negative
2x=-12
to isolate the x you dived by both sides by the 2
x=-6
I doubled checked and it's -6

Answer:
102 textbooks
Step-by-step explanation:
From the above question,
The total amount in donations = $4,111 . They plan to use the money to buy new social studies textbooks. Each textbook costs $40.
If :
$40 = 1 textbook
$4,111 = x text books
Cross Multiply
40 × x textbooks = $4,111 × 1
x = $4,111/40
x = 102.775 textbooks
Since the number of textbooks is whole number and it cannot in be decimal, the number of textbooks they can purchase is 102 textbooks
