A first number plus twice a second number is 2. Twice the first number plus the second totals 10. Find the numbers.

x = 6, y = -2

Step-by-step explanation:

Let the numbers be x and y.

x + 2y = 2

x = 2 - 2y --(1)

2x + y = 10 --(2)

sub (1) into (2):

2(2 - 2y) + y = 10

4 - 3y = 10

y = -2

when y = -2, x = 6

This is a question on simultaneous equations. If you wish to venture further into it/understand this topic better, you may want to follow my Instagram account (learntionary), where I post some of my own notes on certain topics and also some tips that may be useful to you :)

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
