Answer: x = -1/3
----------------------------------------------------------------------------------------------------------------
7x - 11 = -19 + 3x
Let's first get the x isolated to one side, so subtract 3x from both sides:
4x - 11 = -19
Now add 11 to both sides:
4x = -8
Now to get x by itself, divide 4x by 4, and then divide the other side by 4, leaving:
x = -2
Check your work:
7(-2) - 11 = -19 + 3(-2)
-14 - 11 = -19 - 6
-25 = -25
Yep!
Answer:
t = 0.5m + 15
Step-by-step explanation:
0.5m + 15 = t
Hello!
We can put the x values in and see if we get y
Option 1:
Set A: y = 4x - 2
Do the first values
y = 4(-1) - 2
y = -4 - 2
y = -6
Look at the next one to be sure
y = 4(1) - 2
y = 4 - 2
y = 2
So the set A equation is correct we can look at set be now
y = x + 4
y = -5 + 4
y = -1
Try the next one to be sure
y = -2 + 4
y = 2
So the set B equation is also correct
The answer is the first one
Hope this helps!
