Answer:
Line 4
Step-by-step explanation:
6(x+2) = 24
6x+12=24
6x=12
x=2
Answer:
x = 1
y = -2
Explanation:
First, solve for x by subtracting 7y from both sides of the first equation and then divide both sides by -5.
-5x + 7y = -19
-5x + 7y - 7y = -19 - 7y
-5x = -19 - 7y
-5x/ -5 = -19 - 7y/ -5
x = -19 - 7y/ -5
Next, substitute the value of x into the second equation and solve.
6 - (-19 - 7y)/ 5 - 2y = 10
- 6(-19 - 7y)/ 5 - 2y = 10
Then, solve for y
- 6(-19 - 7y)/ 5 - 2y = 10
-6(-19 - 7y) - 10y = 50
114 + 42y - 10y = 50
144 + 32y = 50
32y = 50 - 144
32y = -64
32y/ 32 = -64/ 32
y = -2
Finally, substitute the value of y into the x value we found earlier and solve
x = - 19 - 7y/ 5
x = - 19 - 7 • -2/ 5
x = 1
Answer:
The answer is A. You just have to plug in.
Step-by-step explanation:
5x - y/3= 13
(2,-9) and (3,-6)
5(2) - -9/3 = 13
10 + 3 = 13
13 = 13 (true)
5(3) - -6/3= 13
15+ 2 = 13
17 = 13 (wrong)
Answer:
y = 4x + 6
Step-by-step explanation:
y=mx+b
m= slope
b = y intercept
