Answer 3

To solve the first equation $x + 30 \times 5 = 365$, you need to follow the order of operations, which is often remembered using the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction, from left to right). In this case, you need to perform the multiplication first and then solve for $x$.

1. Multiply: $30 \times 5 = 150$
2. Subtract: $x + 150 = 365$
3. Isolate $x$: $x = 365 - 150$
4. Solve: $x = 215$

So, the solution to the first equation is $x = 215$.

For the second equation $x \div 4 = 100 - 22$, you should first simplify the right side of the equation and then solve for $x$.

1. Subtract: $100 - 22 = 78$
2. Divide: $x \div 4 = 78$
3. Multiply by 4 to isolate $x$: $x = 78 \times 4$
4. Solve: $x = 312$

The solution to the second equation is $x = 312$.
