Use algebraic rules of equations to predict the solution type to the system of equations. Include all of your work for full credit. \(f(x) = \left\{ x+y=−4 y=2x−1 \right.\)

x = -1

y = -3

Step-by-step explanation:

We have two equations:

x + y = −4 (1)

y = 2 * x - 1 (2)

What we will do is substitute (2) in (1) and we are left;

 x + 2 * x - 1 = −4

3 * x = -4 + 1

3 * x = -3

x = -3/3

x = -1

Now, to find out and, I replace in (2), like so:

y = 2 * (- 1) - 1

y = -2 -1 =

y = -3

Therefore, the values are:

x = -1

y = -3

answer: h=5.6 i don't really know how to put into words, so i though i would let you do that. i hope i was able to some

step-by-step explanation:

18 = 6(h)+1/2

18 = 6h+1/2

18-1 = 6h/2

17 = 3h

17/3 = h

h = 5.6
