5 would be the best answer choice
Answer:
x = 7
y = 0
Step-by-step explanation:
→To solve this, you can use the elimination method. To do this, you must have one set of variables that can cancel each other out. In the problem given, we already have positive 4x and -4x, making them cancel out:
4x + 9y = 28
-4x - y = -28
__________
8y = 0
y = 0
<u>→Plug in 0 for y, into an equation:</u>
-4x - 0 = -28
-4x = -28
x = 7
Answer:
Step-by-step explanation:
4x+8=6x-1
<u>-4x . =-4x .</u>
8 = 2x-1
<u>-1+8=2x-1+1 </u>
7=2x
7/2= 2x/2
3.5=x
For example
f(x)=3x+2 and f(x)=x/x-1
Any conversion that goes down to a smaller value
Ex: Kilometer to meter will be x1000
meter to centimenter is x100
BUT going up will be division
Meter to kilometer is /1000
