Answer:
(x,y)=(-13,-12)
Step-by-step explanation:
5x - 7y = 19
7x - 7y = -7 Multiply both sides of the equation by -1
Which then gives you :
5x-7y=19 Sum the equations vertically to eliminate
-7x+7y=7 at least on variable
-2x=26 Divide both sides of the equation by -2
X=-13 Substitute the given value of x into the equation 7x - 7y =-7
7 x(-13)-7y=-7 solve the equation for y
y=-12
Thus gives you (-13,-12)
Hope this was useful!!! Sorry if it's wrong.
Answer:
What is it rounded up to???
Step-by-step explanation:
Answer:
n = 5
Step-by-step explanation:
1) Use power rule: 
.
2) Cancel the base of z on both sides.
2n = 10
3) Divide both sides by 2.
4) Simplify 
to 5.
n = 5
