2(n+3)= 4
n= -1
-1+3=2 then 2x2=4. Sum is an answer to an addition problem so a number and 3 times 2 = 4. Hope this helps and have a great day!
You have to multiply 3x3 since it says 3^2 then subtract 9 from 10 you get 1. Then you have to diving 8x and 1 and you get 1/8
The two ys must be the same. Equate the two right hand sides.
-x + 10 = x + 2 add x to both sides.
10 = x + x + 2
10 = 2x + 2 Subtract 2 from both sides.
8 = 2x Divide by 2
x = 8/2
x = 4
Now solve for y
y = x + 2
y = 4 + 2
y = 6
Use the other equation to check it.
y = - x + 10
y = -4 + 10
y = 6
If it's asking for us to round both to the nearest whole number then divide:
35÷5 = 7 is the correct answer.
