Question

the sum of two numbers is 12. the sum of triple the larger number and four times the smaller number is 40. setup and solve a system of equations to find the nunbers. pls explain how u got the steps to the answer. ty.

Answer 1

*numbers

Answer 2

umm all i can think of is 9 and 3 bc 9x3=27 3x4=12 27+12=39 i hope this helps

Answer 3

9 and 3.25 is the right answer 9x3=27
3.25x4=13
27+13=40

Answer 4

please mark it a medal

Answer 5

where did u get 3.25 from?

Answer 6

it says 2 numbers
so 9 and 3.25

Answer 7

i was just random thinking

Answer 8

but 9 and 3.25 doesn't equal 12

Answer 9

oh yea sorry ill rethink

Answer 10

okay

Answer 11

its 12 and 1
12x3= 36
1x4=4
36+4=40

Answer 12

thats it i earn a medal

Answer 13

12 and 1 doesn't equal 12

Answer 14

The problem says to set up a system of equations. Let’s let our two numbers be x and y. Let’s let x be the smaller one and y be the larger one.

the sum of two numbers is 12 —> x + y = 12

the sum of triple the larger number and four times the smaller number is 40 —> triple the larger one = 3y, and four times the smaller one = 4x. Their sum is 40. The second equation is therefore 4x + 3y = 40

So our system now is

x + y = 12
4x + 3y = 40

Solve using substitution, elimination, or graphing.
