X − y = 12<br> x + 2y = 21

olga55 [171]

Answer: x=15, y=3

Step-by-step explanation:

Subtracting the two equations, we get -3y=-9, meaning y=3.

Substituting this into the first equation, we get that x-3=12, and thus, x=15.

lakkis [162]

$- 0.25z = - 1.25 \\ \Leftrightarrow \: z = \frac{ - 1.25}{ - 0.25} = \frac{ - \frac{5}{4} }{ - \frac{1}{4} } = 5$

When the product of 6 and the square of a number is increased by 5 times the number, the result is 4.

il63 [147K]

Let $x$ be the unknown number. Its square is $x^2$ . The product of 6 and the square of the number is $6x^2$ . Increase this by 5 and you get $6x^2+5$ .

If this has to equal 4, you have $6x^2+5=4$
