Commutative property of addition for 5x+20+3x+9x+7

The commutative property lets you group like terms together:

... 5x +3x +9x +20 +7

Step-by-step explanation:

If we divide the expression into 4 groups:

...[5x] +(20) +(3x +9x) +[7]

according to the commutative property of addition, we can swap the groups in curved parentheses.

... [5x] +(3x +9x) +(20) +[7]

The distributive property lets you combine x terms:

... (5 +3 +9)x +27

... 17x +27 . . . . . . the simplified form of the expression

y=−9/2x+10

step-by-step explanation:

let's solve for y.

0−9x−2y=−20

step 1: add 9x to both sides.

−9x−2y+9x=−20+9x

−2y=9x−20

step 2: divide both sides by -2.

−2y

−2

=

9x−20

−2

y=
