Answer:
A. x=2, y = 7.
B. (2, 7).
Step-by-step explanation:
A. You can eliminate y by subtracting the equations:
y = 8x - 9
y = 4x - 1 Subtract:
0 = 4x - 8
4x = 8
x = 8/4 = 2.
Now substitute for x in the first equation:
y = 8(2) - 9 = 7.
Check in the second equation:
y = 4x - 1
7 = 4(2) - 1 = 7. Check is OK.
B. On the graph they will intersect at the point (2, 7).
They will intersect here because the values x=2 and y=7 satisfy both the 2 equations.
Answer:
g = - 5
Step-by-step explanation:
2 - 8g = -3 - 9g
Add 9g to both sides of the equation:
2 - 8g + 9g = -3 - 9g + 9g
2 + 1g = - 3
Subtract 2 from both sides of the equation:
2 - 1g - 2 = - 3 - 2
1g = -5
Divide both sides of the equation by 1:
g = -5
