Name the property used in (5+2)+n=7+n

Mathematics
1 answer:
S_A_V [24]3 years ago
6 0

Answer:

Step-by-step explanation:

Additive identity is a property that involves the sum of two or more integers in an equation without compromising the equality of the equation.

Given the equation

(5+2)+n = 7+n

We can see that the right hand side of the equation is derived from the left hand had by addition of the values in parenthesis.

Given the right hand side;

= 5+2+n

= (5+2)+n

adding the expression in parenthesis will give;

= 7 + n

Since we added the expression in parenthesis to arrive at the expression at the right hand side, hence additive identity was used in the calculation.

Answer:

x=65

Step-by-step explanation:

Step 1: Add -3 to both sides.

√x−1+3+−3=11+−3

√x−1=8

Step 2: Solve Square Root.

√x−1=8

x−1=82(Square both sides)

x−1=64

x−1+1=64+1(Add 1 to both sides)

x=65

Check answers. (Plug them in to make sure they work.)
