Step-by-step explanation:
-4.5x -2y = -12.5 -------(1)
3.25x -y = -0.75 --------(2)
From (2) we can make y the subject of the relation
y = 0.75+3.25x -------(3)
Input 0.75+3.25x into y in (1)
-4.5x -2(0.75+3.25x) = -12.5
-4.5x -1.5- 6.5x = -12.5
-4.5x -6.5x -1.5 = -12.5
-11x = -12.5 +1.5
-11x = -11
x = 11/11
x = 1
If x = 1,substitute 1 into x in (3)
y = 0.75+3.25x
y = 0.75 +3.25(1)
y = 0.75 +3.25
y = 4
x = 1,y = 4
Answer:
x= 1.5 Hope that helps!
Step-by-step explanation:
1. 12(5x-4.5)=36 First Divide both by 12 5x-4.5-36/12 = 3
2. 5x-4.5=3 add 4.5 to both sides
3. 5x= 3+4.5 = 7.5
4. 5x=7.5 divide both sides by 5 x=7.5/5= x=1.5
So, x=1.5 would be your answer. Can you make me Brainliest Please

Step-by-step explanation:
Hello :D
$40.00 x 3 = $120.00
$20.00 x 2 = $40.00
$120.00 + $40.00 = $160.00
$400.00 - $160.00 = $240.00
There is $240.00 left in the account.
Umm, That's A lot Of Homework...
