Use elimination to solve the system x plus 7y equals 16 and 3x - 7y equals 4?
x+7y=16 ---------------------------1 3x- 7y=4 ---------------------------2 ------------------------------------------------------------------------------------------------------------------ 1+2 x+7y=16 3x-7y=4 4x=20 x=5 substitute x = 5 in x+7y=16 (5)+7y=16 7y=11 y=11/7
X 7y 39 3x - 2y 2?
x+7y=39
16 7y -8?
simplify the expression 16+7y-8 rewrite as 7(y-8)7•y= 7y 7•8= 56 7y-56 = -49y answer= 16+ (-49y)
What is 7y - 46 in a algebraic expression?

If 2ax - 5x equals 2 then x is equivlent to?
x = 1 divided by (a - 2.5)
Multiply and simplify y-7y-5?
-2
What is the answer to 5y plus 7y?
The given expression can be simplified to: x-12y
Does an expression have an answer?
A mathematical expression does not have an answer, if it is algebraic and all of the terms are unlike. For example, x+7y does not have an answer because there are no definite solutions, and there is no possibility to combine like terms. However, the expression 2x+7y+3x does have an answer, but the solution is merely the combination of like terms. (5x+7y)
What is the answer to -2x-5y plus 3x-7y?
The given expression can be simplified to: x-12y
How do you write 7y 46 in algebraic expression?

What are four expressions equivlent to the expression 33y-11y?
44
What is -7y plus x?
x = 7y x/7 = y
Use elimination to solve the system x plus 7y equals 16 and 3x - 7y equals 4?
x+7y=16 ---------------------------1 3x- 7y=4 ---------------------------2 ------------------------------------------------------------------------------------------------------------------ 1+2 x+7y=16 3x-7y=4 4x=20 x=5 substitute x = 5 in x+7y=16 (5)+7y=16 7y=11 y=11/7
What is 13x plus 2y -10x -7y?
To simplify the expression 13x + 2y - 10x - 7y, you first combine like terms. Group the x terms together and the y terms together: (13x - 10x) + (2y - 7y). This simplifies to 3x - 5y. Therefore, the simplified expression is 3x - 5y.
What is the answer to simplify 5x-6y-2x-y?
The simplified expression is 3x - 7y.
X 7y 39 3x - 2y 2?
x+7y=39
