Answer:
9=x
Step-by-step explanation:
If 7x+3=24, that means x would be 3 so if you take 5-4x then that would be -7.
-30-27= -57
When both numbers are negative, they are “added” in a sense, but remain negative.
-5-(-4)= -1
You have to multiply the (-4) by the “invisible” -1 on the outside before you add/subtract.
