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)

Answer:

$- 39xy + 12 {y}^{2}$

Step-by-step explanation:

1) Simplify 6x × 2y to to 12xy.

$12xy - 3xy - 24xy \times 2 + 12 {y}^{2}$

2) Simplify 24xy × 2 to 48xy.

$12xy - 3xy - 48xy + 12 {y}^{2}$

3) Collect like terms.

$(12xy - 3xy - 48xy) + 12 {y}^{2}$

4) Simplify.

$- 39xy + 12 {y}^{2}$

Thus, The answer is -39xy + 12y².
