b
Step-by-step explanation:
Oooh I don't know the exact wording, but it is the property that states that the order of the numbers in the equation can be switched and still equal the same thing as long as the signs are still kept.
Answer:
y = 2
Step-by-step explanation:
x + 5y - 10 = 0
X = 4y - 8
since x is given as = 4y - 8 we can use this in first equation
replace x with 4y - 8
x + 5y - 10 = 0 ➡ 4y - 8 + 5y - 10 = 0 add like terms
9y - 18 = 0 add 18 to both sides of the equation
9y = 18 divide both sides by 9
y = 2
