First Equation:
0.6 +(0.4+0.9) =n
Step 1: do parentheses first:
0.4+0.9 = 1.3
Step 2: Add 0.6 + 1.3
0.6 + 1.3 = 1.9
n= 1.9
Second Equation:
(1.57 + 0.75) + 0.25 + n
Step 1: do parentheses first:
1.57 + 0.75 = 2.50
Step 2: Add 2.50 + 0.25 = 2.75
Step 3: Add 2.75 and n = 2.75+n
Final Answer:
1.9 +2.75+n = 4.65 +n
Hope this helps!!
