Answer:

Step-by-step explanation:

Assuming we are trying to find x, we know that x and 10 together are equal to 23, so if we subtract 10 from both sides to have x by itself on one side,

$10+x=23\\10-10+x=23-10\\x=13$

and its value on the other.

Answer:

x = 13

Step-by-step explanation:

This is a simple algebraic problem. Since x must be left by itself in order to solve, we subtract 10 on both sides, giving us the final answer of x = 13.

Answer:

y = 1

x = -3

Step-by-step explanation:

9x + 2y = 3

-x - y = -12 (multiply second equation with 9)

9x + 2y = 3

-9x - 9y = - 108 (add these to up)

-7y = -105

y = 15 use this to find x

9x + 2y ➡ 9x + 30 = 3 ➡ 9x = -27 ➡ x = -3

What is the solution to the system of equations below? y= -4/5 x + and y = –30

Naya [18.7K]

Answer:

$x=37.5$

Step-by-step explanation:

We need to find the solution to the following system of equations:

$y = -\frac{4}{5} x$ and $y=-30$

By plugging the value of 'y' into the first equation we have that:

$-30 = -\frac{4}{5} x$ ⇒ $30=\frac{4}{5} x$

Solving for 'x' we have:

$x=37.5$

So, the solution to the system of equation is: (37.5, -30)

Y and x have a proportional relationship, and y = 12 when x = 5. What is the value of y when x = 8?

serious [3.7K]

When x = 8 y = 15

The way to figure this out is to subtract 12 by 5. That’s 7 so there’s a difference of 7 between both of the numbers.

Hope this helped!
