Answer:

(4, 5)

Step-by-step explanation:

y = 2x - 3

y = 7 - 0.5x

y is already isolated on both equations, set them equal to each other:

2x - 3 = 7 - 0.5x

add 3 to both sides:

2x = 10 - 0.5x

add 0.5x to both sides:

2.5x = 10

divide by 2.5:

x = 4

plug in 4 for x on either equation and solve for y:

y = 2(4) - 3

y = 8 - 3

y = 5

Answer: x = 5

Step-by-step explanation:

We can set up an equation to solve for x:

3x + 4 = 19

We can subtract 4 from both sides:

3x = 15

We can divide both sides by 3:

x = 5

(4r^6 + 2r^5 - 8r^4) ÷ r^4

Basile [38]

The solution is $2(2r^2+r-4)$

Explanation:

The given expression is $\frac{4r^6+2r^5-8r^4}{r^4}$

We need to determine the solution of the given expression.

The solution of the expression can be determined by dividing the terms.

Thus, we have,

$\frac{4r^6+2r^5-8r^4}{r^4}$

Let us factor out the common term $2r^4$ from the numerator.

Thus, we get,

$\frac{2r^4(2r^4+r-4)}{r^4}$

Cancelling the common terms, we get,

$2(2r^2+r-4)$

Thus, the solution of the expression is $2(2r^2+r-4)$
