98+a=425
Subtract 98 from both sides;
98-98 + a= 425-98
a=327

M-708=292
Add 708 to both sides;
M-708+708= 292+708
M=1000

Just do inverse operation, where if you have a subtraction sign in front of a number, you add that same number to it, vice versa for addition. just make sure to do the same to the number on the other side of the equal sign though.

x-9=10
x-9+9 = 10+9
x=19

x+9=10
x+9-9 = 10-9
x=1

2. An expression is shown.

laiz [17]

Adding parentheses in the component $9\div 3$ of the expression may bring an output of 48.

<h3>Procedure - Application of hierarchy rules in a arithmetic expression</h3>

In this question we should make use of hierarchy rules represented by the use of parentheses. The parentheses oblige to make operations inside it before making it in the rest of the formula.

Now we decide to add parenthesis in the component $9\div 3$ such that the result of the entire expression is 48. We proceed to present the proof:

$2 \times 8 \times (9\div 3)$
