LAW 2: The second law of indices tells us that when dividing a number with an exponent by the same number with an exponent, we have to subtract the powers. In algebraic form, this rule is as follows . The a represents the number that is divided by itself and m and n represent the powers.
Because the ratio is 1 to 3. It means that For every one apple there are 3 oranges. So If there are 2 apples, there would n 6 oranges. If there are twelve apples, there would be 36 oranges. To find the number of oranges for the amount of apples, just multiply the number of apples by 3.
|2x + 12| = 18
First, break down the problem into 2 equations . / 2x + 12 = 18 and -(2x + 12) = 18
Second, solve the first equation. /

Subtract 12 from both sides. /

Subtract 18 - 16. /

Divide both sides by 2. /

Simplify. /
Third, solve the second equation. / -(2x + 12) = 18
Simplify your brackets. /

Add 12 to both sides. /

Add 18 + 12. /

Divide both sides by -2. /

Simplify. /

Simplify. /
Fourth, collect the solutions. /
