Answer:
(-1, -3) and (1, 1)
Step-by-step explanation:
Use a graphing calculator to graph out both lines:
(See picture)
Both lines intersect at points (-1, -3) and (1, 1). These are the solutions for the system of equations.
Answer:
a = 22
b = 7
Step-by-step explanation:
Let the two numbers be represented as a and b.
a + b = 29
a - b = 15
Using elimination method
Add both equations
2a = 44
Divide both sides by 2 to get a
2a/2 = 44/2
a = 22
Now substitute a = 22 in any of the equations to get b .
Using the first equation, we have
a + b = 29
22 + b = 29
Subtract 22 from both sides of the equation
22 - 22 + b = 29 - 22
b = 7
Therefore the two numbers are 22 and 7
