Question

Solve the pair of simultaneous equations.
3x-2y=10
2x+5y=13

Answer 1

hmm lets see

Answer 2

first solve the top equation for y. Can you do this?

Answer 3

nope

Answer 4

can you try?

Answer 7

can u make y the subject of the formula? @Tashagaye

Answer 8

of which formula @hubertH

Answer 9

@Outkast3r09 i dnt understan why cant u help me i dnt understan

Answer 10

the question

Answer 11

Well first you need to go back and review the properties or equalities before you try to handle this problem

Answer 12

These properties simply state that basically, if you use a sign on one side of an equality, you must do the same sign on the right side to keep them equal to eachother (this includes subtraction, addition, multiplication, division, exponents, radicals)

Answer 13

Addition

\[x=y\]
\[2=2\]
\[x+2\neq y\]
\[2+2\neq 2\]
\[x+2=y+2\]
\[4=4\]

Answer 14

3x - 2y =10 so minus 10 both sides
3x-2y-10=0 so add 2y both sides
3x-10=2y divide both sides by 2
3x-10/2=y

Answer 15

hubert, especially don't give the answer in this case... properties of equalities are needed for almost everything

Answer 16

i still dnt get ur working out @Outkast3r09

Answer 17

alright so if you have something such sa

\[x=y\]

in which a set such as (2,2) works, if you manipulate one side of the equation, the equality no longer stands. See how when i added two to one side and not the other, the equality broke and it was no longer equal. However when i added two to both sides it kept it equal

Answer 18

so using , addition subtraction division and multiplication, you want to get

\[y=something\] for the first equation
