Answer:
Solution (8 , 17).
Step-by-step explanation:
Given : y = 3x − 7 and y = 2x + 1
.
To find : What is the solution to the system of equations.
Solution : We have given
y = 3x − 7 --------(1)
y = 2x + 1 ---------(2).
Plug the value of y of equation 2 in equation 1.
2x + 1 = 3x - 7.
Subtracting both sides by 1
2x + 1 - 1 = 3x - 7 - 1.
2x = 3x - 8.
On subtracting both sides by 3x.
2x -3x = - 8.
-x = -8
On Dividing both sides by -1
x = 8.
Now plug the x = 8 in eq 1.
y = 3(8) -7.
y = 24 - 7.
y = 17.
Solution (8 , 17).
Therefore, Solution (8 , 17).
