5x-2y=30 complete the missing solution to the equation

astra-53 [7]

Answer:

I would have to go with x = 8 and y = 5, meaning the solution is (8, 5).

Step-by-step explanation:

$5x - 2y = 30$

$5(8) - 2(5) = 30$

$40 - 10 = 30$

$30 = 30$

mr Goodwill [35]

Variables - a quantity that may change, depends on the context of the math problem. Ex: x,y
Terms - a variable, or constant, that is multiplied by a variable or variables.
Ex: 5x + 2 + 3y <-- has 3 terms
Coefficient - the constant that multiplies the variable and is next to a variable, Ex: (5x) <-- coefficient is 5
Constants - A fixed value such as 5, 6, 7, etc

Help 10 POINTS MATH IS NOT MY STRONG SUIT

Masja [62]

Answer:

infinite number of solutions

Step-by-step explanation:

Work with the second equation. Subtract 8x from both sides.

- 4y + 8x - 8x = -8x - 12 Collect like terms.

-4y = - 8x - 12 Divide by - 4

-4y/-4 = - 8x/-4 - 12/-4

y = 2x + 3

That is exactly the same line as the first given. There is an infinite number of solutions.
