Answer:
-7
Step-by-step explanation:
2x+3=x-4
Let's start by subtracting 3 from both sides
2x=x-7
Now, subtract x from both sides
x=-7
Let's plug it in to make sure!
2(-7) +3= (-7)-4
-11=-11
x= -7
You subtract both sides by x meaning the x on the right side will turn to zero and then you subtract both sides by 3
I don't know. I think I need the picture that is associated with it.
x=m2/10 − 1/5
x=m2/9 − 8/9
<em>In 4 hours.</em>
Just equate f(x) = g(x). So:
15x + 90 = 30x + 30
60 = 15x
<em>x = 4 hours.</em>
