A) $355 + $18x = $514 + $15x
B) $355 + $18x = $514 + $15x
355 -355 + 18x = 514 -355 + 15x
18x = 159 + 15x
18x-15x=159+15x-15x
3x = 159
3x/3=159/3
x = 53
C) $355 + $18(53) = $1309
$514 + $15(53)= $1309
D) You can check your answer by taking what x equals and plugging back into the original formula of $355+$18x=$514+$15x. Then solve making sure the left side equals the right side.
$355+$18x=$514+$15x
$355 + $18(53)=$514 + $15(53)
$1309 = $1309
Answer:
(4,8)
x=4
y=8
Step-by-step explanation:
x is the first number
y is the second number
x+y=12
x-y= -4
Let's add y and 4 to the second equation to get y by itself
x+4=y
We can substitute this value in for y in the first equation
x+x+4=12
2x=8
x=4
We can then use x=4 and plug that into any equation
4+y=12
y=8
The answer is (4,8)
Yo sup??
0.000000001=1*10^(-9)
since the power is (-9) hence it's called as a nano second.
This is also known as 'One nano second'
Hope this helps.

Hi ki kinda time to get yer guy
Y=-2*(-2)-1
=4-1
y=3
Hope that answer can help you
