Answer:
(2,1)
Step-by-step explanation:
If you solve for the first variable (x) then you discover that your x coordinate is 2. You can then substitute two in for x in the equation and discover that your y-coordinate is 1 meaning your point or intersection is (2,1).
x + 3y = 5
5x - 3y = 7
Add up both equations, then:
6x = 12
=> x = 2
=> y = (5 - 2)/3 = 1
17 i think
518
i don't know if this needs much explaining.
5(2+x)=5
or, 10+5x=5
or, 5x= -5
or, x= -1
Hope it helps
