The sum of two numbers is 19. Three times the larger is 3 more than 6 times the smaller. Find the numbers.

ella [17]

Answer:

x=6

y=13

Step-by-step explanation:

The statement says that:

$3x=6y+3\\$

Been y the smaller and x the larger. The other equation that we have is the summation of the two numbers. Then we have 2 equations and 2 unknowns

$1. 3x=6y+3\\2. x+y=19\\$

Solving the equations the answers is x=13 and y=6.

strojnjashka [21]

Answer:

The answer is: $2x^2-7x-2$

Step-by-step explanation:

we are asked to subtract $7x-9$ from $2x^2-11$

so, $2x^2-11-(7x-9)\\=2x^2-11-7x+9\\=2x^2-7x-2$ .

Hence the desired result is: $2x^2-7x-2$ .
