y= x+4
y= -x+2
Solve the system of linear equations.
2x+y=5
x+y=4
We need to solve 2x+y=5 for y
let's start by adding -2x to both sides
2x+y-2x=5-2x
y=-2x+5
Now substitute -2x+5 for y in x+y=4
x+y=4
x-2x+5=4
-x+5 =4
Add -5 to both sides so we can find the value for x
-x+5-5=4-5
-x=-1
We know that x can not stay with the negative sign so to eliminate that we need to divide both sides by -1
-x/-1= -1/-1
x=1
Now we have the value for x :)
We need to find the value for y by substitute 1 for x in y=-2x+5
y=-2x+5
y= (-2)(1)+5
y= -2+5
y= 3
Final answer : x=1 and y=3
(1,3)
I hope that's help :)

Answer:
Sample Response: When evaluating a power with a negative base, the solution is positive or negative depending on whether the exponent is odd or even. If odd, the value will be negative. If even, the value will be positive.
Step-by-step explanation:
Solution of the given equation is x=2 and 0
An equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
