Answer:
(2, )
Step-by-step explanation:
Given the 2 equations
2x + 3y = 17 → (1)
3y = 15 - x → (2)
Substitute 3y = 15 - x into (1)
2x + 15 - x = 17, that is
x + 15 = 17 ( subtract 15 from both sides )
x = 2
Substitute x = 2 into either of the 2 equations for corresponding value of y
Substituting in (1)
2(2) + 3y = 17
4 + 3y = 17 ( subtract 4 from both sides )
3y = 13 ( divide both sides by 3 )
y =
Solution is (2, )

4. 13-5=8 and the square root of 8 is 2.828...
Irrational numbers has infinite numbers
Answer:
(-8,-7)
Step-by-step explanation:
assuming that the top part of the y-axis is north and the bottom part is south
we know west is to the left and that means -5 so -3-5=-8 meaning our coordinate is (-8,-7)
You add 11 to both sides first!
