Solve the system using the elimination method
2x + 3y = 12
15x -3y = 39

x=3 y=2

Step-by-step explanation:

Step one:

Add both equation

2x+3y=12

+ 15x-3y=39

17x=51

x=3

Step 2: After finding the answer for x, plug it into the first equation to find the value of y

2(3)+3y=12

6+3y=12

3y=6

y=2

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
