Answer:
<h2>x=(2/3)y-4</h2>
Step-by-step explanation:
You mean:
3x - 2y = -12
solve:
3x=2y-12
x=(2y-12)/3
<h2>x=(2/3)y-4</h2>
Answer:
<h2>y = 0 or y = -2/3</h2>
Step-by-step explanation:
The product is zero if one of the factors is equal to zero. Therefore

Answer:
|x| + |y| = 29
Step-by-step explanation:
We have been given the expression;
|x| + |y|
We are required to evaluate the above expression if;
x = 16 and y = 13
The parallel vertical lines imply that we are dealing with the absolute value of x and y;
|x| + |y| = |16| + |13|
= 16 + 13
= 29
