Answer:
<h2>-5 + 7x</h2>
Step-by-step explanation:
The Commutative Property states that the order of addition or multiplication does not matter.
EXAMPLE 1 : 1 + 2 = 2 + 1 = 3
EXAMPLE 2: 3 x 4 = 4 x 3 = 12
It appears that we cannot use the commutative property on this expression. But we can. First, we need to change - 5 = + -5.
7x - 5 = 7x + -5
Because we now have addition, we can prove the commutative property.
-5 + 7x = 7x + -5
I'm always happy to help :)
Answer:
y=18 x=15
Step-by-step explanation:
1.
multiplyboth sides by 3
2(x-6)=18
divide both sides by 2
x-6= 9
add 6 on both sides
x=15
2.
add 6 on both sides
2/3y= 12
multiply both sides by 3
2y=36
divide both sides by 2
y=18
