Answer:
3+7-4=6
Step-by-step explanation:
replace the h with -7.
3+ [-(-7)]+(-4)
simplify. two negatives make a positive, causing the [-(-7)] to simply become 7.
the +(-4) simplifies to -4.
so...
3+7-4
from here its really really easy, just simple add and subtract.
3+7=10
10-4=6
If it helped, id really appreciate brainliest :)

Answer:
x = 13
Step-by-step explanation:
For this problem, we will simply uses properties of addition and multiplication to isolate the x variable for the following equation.
4x - 7 = 45
Now consider the following. First, we must isolate the x term by adding 7 to both sides.
4x - 7 = 45
4x -7 +7 = 45 +7
4x = 52
Second, let's further isolate x by multiplying both sides by 1/4 to create a coefficient of 1 Infront of the x variable.
4x = 52
(1/4) * 4x = 52 * (1/4)
x = 13
Hence, we have solved the equation 4x-7=45 where x=13.
Cheers.
