x is 90 y is 43 im pretty sure
Given :96 13 13 96 .
Sings of operations are not visible in the given problem.
Let us take multiplication sign × first and then we will take plus sign.
Let us take multiplication sign × first.
96 × 13 = 13 × 96.
The number 96 and 13 just changed their positions.
Also, on changing those positions, the values of product doesn't change.
So, we can see that a*b=b*a property is being applied there.
a*b=b*a represents Commutative Property of Multiplication.
Therefore, 96 × 13 = 13 × 96 represents Commutative Property of Multiplication.
If we take plug sign in between, we would have expression
96+13 = 13+96.
Still on changing positions of numbers the values of sum remain same.
So, we can apply property represented by a+b=b+a.
And that is Commutative Property of Addition.
Therefore, 96+13 = 13+96 also represents Commutative Property of Addition.
Let x= hours spent job A
let y= hours spent job B
14x + 12.50y = 600
x + y = 45
x=-y +45
14(-y+45) + 12.5y = 600
-14y + 630 + 12.5
-1.5x + 630 = 600
-1.5x=-30
x=20
(20) + y = 45
y= 25
20 hours job A, 25 hours job B
