Question

Please helppppppp triple sad face!!!!

Elimination method.

5x + 2y = 55
2x - y = 19

Answer 1

you want to get x or y?

Answer 2

both

Answer 3

this one is tricky very tricky

Answer 4

okay so you have to work on one equation and have only one variable
go to the second equation and move y to the other place it will be y=2x-19
so now you can eliminate y in the first equation with 2x-19
it will be 5x+2(2x-19)=55
simplify .. 5x + 4x-38+55 >> 9x=93 then x equals 31/3

Answer 5

hang on lemme try this by myself too

Answer 6

wait you lost me

Answer 7

@kropot72

Answer 8

the answer is x + y= 12 i need to know why

Answer 9

sorry i lost connection
well in case you havent known it yet
we got x= 31/3
then eliminate in the second equation ... 2(31/3) - y = 19
simplify ... 62/3 - y =19 then switch places of y and 19 with opp signs to get y like that
62/2 - 19 = y then y equal 5/3

Answer 10

now you want to know x + y
x = 31/3 y=5/3
so substitute
31/3 + 5/3 equals 12

Answer 11

i hope its clear now :)
