Answer:
7/3
Step-by-step explanation:
5 + 2 = 7
8 - 5 = 3
7/3
Well I'd assume you mean this:
If I choose 20
20+5x(-4)-3
5x-4 =-20
20 +(-20) - 3
0-3 is -3
and so on
Answer:
no
Step-by-step explanation:
Just plug it in
-4(4) + 3(1) = 2
-16 + 3 = 2
-13 = 2
Without even solving the second equation, the answer is no because -13 does not equal 2
Answer: The equation is true
Step-by-step explanation:
Since x=3 and y= 5
Substitute the values for x and y
y=2x-1
5=2(3)-1
5=6-1
5=5
⇒The equation is true
