<h3>What are word problems in algebraic equations?</h3>
Word problems leading to algebraic equations are real-life problems that can be interpreted and solved with the use of variables and arithmetic operations.
From the information given:
- Let us assume that the age of the house is (m)
Now, the amount paid on the mortgage is:
m + 21
This is equal to 4 times as old as it is now;
i.e.
m + 21 = 4m
m- 4m = -21
-3m = -21
m = -21/-3
m = 7
Therefore, we can conclude that the house is 7 years old.

Answer:
Area of the figure = 350 cm²
Step-by-step explanation:
Area of the given figure in the picture = Area of big rectangle - Area of small rectangle A
Area of big rectangle = Length × Width
= 25 × 15
= 375 cm²
Length of mall rectangle = 25 - (5 + 15)
= 5 cm
Width of small rectangle = 5 cm
Area of small rectangle = 5 × 5
= 25 cm²
Area of the figure = 375 - 25
= 350 cm²
No solution: 1/2y + 3.2 = 20, 15/2 + 2z -1/4 = 4z + 29/4 - 2z, 1.1 + 3/2x + 2 = 3.1 + 3/4x, and 4.5r = 3.2 + 4.5r. One solution: 2x + 4 = 3x + 1/2
The complete question is attached below.
<h3>What is the linear system?</h3>
A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.
If the value of the variable is zero, then the no solution.
If the value of the variable is one, then the one solution.
If the value of the variable is infinity, then the infinite many solutions.
No solution: 1/2y + 3.2 = 20, 15/2 + 2z -1/4 = 4z + 29/4 - 2z, 1.1 + 3/2x + 2 = 3.1 + 3/4x, and 4.5r = 3.2 + 4.5r.
One solution: 2x + 4 = 3x + 1/2
