HELP ASAP PLEASE!!!Explain how to tell if a point is a solution for a system of equations.

Answers

Answer 1

Answer:

Explanation:

When you put the solution values into each equation, the equation becomes a true statement. If all equations become true statements, the point is a solution to the system.

_____

For example, consider the system of equations ...

x + y = 6
x - y = 4

The point (x, y) = (5, 1) is proposed as the solution. When we put those values into the equations, we get ...

5 + 1 = 6 . . . . . true

5 - 1 = 4 . . . . . .true

(x, y) = (5, 1) is the solution to this system of equations. (Since it is a system of two independent linear equations in an equal number of unknowns, we know there is only one solution.)

A-b=4 and a+b=6 find a²+b² and ab

Answers

Answer:

...a-b=4

a+b=6

→2a=10

→a=10/2 =5

we calculate b:

a-b=4

5-b=4

-b=4-5

b=1

→a=5; b=1

a²+b² = 5²+1² = 25+1 = 26

ab =5*1 = 5
