C , a relationship between two variables can be expressed by an equation in which one variable is equal to a constant.
Answer:
Step-by-step explanation:
Lets say there's a number 'x' and there's an expression 
where 'a' & 'b' are also numbers , <u>the simplified form of the expression is </u>
<u>.</u>
So ,
<u>4h + 7 = 4h - 3</u>
Subtract 4h from each side: 7 = -3
There is no value of ' h ' that can make this a true statement,
so the equation has no solution.
