So the two numbers can be represented as x and y
so x is first and y is second
y=2(x)-8
so y=2x-8
IF THEY ARE CONSECUTIVE
If they are consecutive numbers then
x+1=y
subtitute
x+1=2x-8
subtract x from both sides
1=x-8
add 8 to both sides and get
9=x
put it into the equation and get
y=2(9)-8
y=18-8
y=10
so x=9
y=10
IF X AND Y ARE CONSECUTIVE INTEGERS (1,2,3,4 not 2.3 or 1,3,5,8)
7/10 = x/12 which mean you need to multiply each side by 12 to find x. So the answer would be X= 8.4
15x-3y=12
<u>y=5x—4
</u>I'm also not sure what your question is, but this is what I got by solving it like a regular equation.
15x-3(5x-4)=12
15x-15x+12=12
0=12-12
0=0
4x-y=-4
<span><u>-8x+2y=2</u>
</span>
-y=-4-4x /: (-1)
y=4+4x
-8x+2y=2
-8x+2(4+4x)=2
-8x+8+8x=2
0=-6
Answer:
3 x 5 is 15 so it would be 3:15
5 x 5 is 25 so it would be 5:25
Step-by-step explanation:
Just multiply by 5 for each one
3 x 5 is 15 so it would be 3:15
5 x 5 is 25 so it would be 5:25
