Answer: (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
Answer:
x=6 and y=5
Step-by-step explanation:
2x+y=17 equation1
3x-3y=3 equation2
multiplying equation 1 by 3 so that 3y and 3y got cancelled and we can find the value of x
3(2x+y=17) ⇒ 6x+3y=51 equation3
adding equation 3 and equation 2
6x+3x+3y-3y=51+3
9x=54
dividing 9 on both sides
9x/9=54/9
x=6
put the value of x in equation 1 to find the value of y
2(6)+y=17
12+y=17
12-12+y=17-12
y=5
put the values in the equation 1 if they give the same answer as R.H.S
so they are correct
i have checked the values it is correct
i hope this will help you :)
