Question

a=4,b=-3 and c=0
Find x=a+b+++--c+++b-c++; and x + = ++b + ++a + -- c + a;​

Answer 1

Answer:

Let's solve for x.

a+b−c+b−c+x=b+a−c+a

Step 1: Add -a to both sides.

a+2b−2c+x+−a=2a+b−c+−a

2b−2c+x=a+b−c

Step 2: Add -2b to both sides.

2b−2c+x+−2b=a+b−c+−2b

−2c+x=a−b−c

Step 3: Add 2c to both sides.

−2c+x+2c=a−b−c+2c

x=a−b+c
