y=-2x+8
y=x-1
Solve y=-2x+8 for y
Substitute -2x+8 for y in y =x-1
y=x-1
-2x+8=x-1
Add -x to both sides
-2x+8+-x=x-1+-x
-3x+8=1
Add -8 to both sides
-3x+8+-8=1+-8
-3x=-9
Divide both sides by -3
-3x/-3=-9/-3
x=3
Substitute 3 for x in y =-2x+8
y=-2x+8
y=(-2)(3)+8
Simplify both sides of the equation
y=2
Answer : y=2 and x=3
(3,2)
I hope that's help !
Kim's age is twice of that of her sister. We'll let k2 = Kim and k = Kim's sister.
So, k2. When you add Kim's age to her sister age you get 36.
Because Kim is twice the age of her sister k2. And because it said 'add' then we put a + sign. k2 + s = 36. Now let's solve it.
k2 + k = 36 < Given
3k = 36 < Combine like terms
k = 12 < Divide both sides by 3
We know Kim's sister is 12 y/o but what about Kim herself? Earlier we assigned Kim to k2. Substitute 12 for k and you get 12(2) = 24
Kim's sister is 12 y/o and Kim is 24 y/o
