A number is twice the other number. The sum of four times the smaller number and three times the larger number is 10. Find the numbers. Please teach me how to do this. I'll give 90 points.

1 and 2

Step-by-step explanation:

Let the first number be x

Let the other number be y

x = 2yeqn 1

From eqn 1, the smaller number is y while the bigger number is x.

3x + 4y = 10 eqn 2

Substitute x = 2y into eqn 2

3(2y) + 4y = 10

6y + 4y = 10

10y = 10

Divide both sides by 10

y = 10/10

y = 1

Substitute y= 1 into eqn 1

x = 2y

x = 2(1)

x = 2

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.

the answer is a.
