Answer:
Two numbers are 38 and 10
Step-by-step explanation:
Let x and y are the two numbers
One number is 18 more than twice the other number.
The sum of the numbers is 48.
Plug in y =2x+18
Subtract 18 from both sides
divide both sides by 3
x=10
Two numbers are 38 and 10

Answer:
-5
Step-by-step explanation:
4+2(x-4) = -7(x+7)
First, work out parenthesis: 4+ 2x-8 = -7x -49
Combine like terms: 2x-4= -7x-49
now isolate x by first adding 49 to each side: 2x+45= -7x
Then subtract 2x from each side: 45= -9x
Last, divide both sides by -9:
x= -5
