Solve the simultaneous equation:2x+y=17;3x-3y=3.

(x,y) (6,5)

Step-by-step explanation:

2x + y = 17

3x - 3y = 3

Divide both sides,

2x + y = 17

x - y = 1

Eliminate one variable by adding

3x = 18

x = 6

Substitute the value of x

3(6) - 3y = 3

-3y = 3-18

y = 15-3

y = 5

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl

answer: none of these answers are correct only the second half is
