Solution: (2,8)
Using the elimination method set up the system of equations like:
y = x + 6
y = 3x + 2
Eliminate the x-variable by multiplying the top equation by -3
-3y = -3x -18
y = 3x + 2
Combine terms:
-2y = -16
-y = -8
y = 8
Plug in 8 to one of the first equations for y
8 = 3x + 2
6 = 3x
x = 2
Solution: (2,8)
Answer:9
Step-by-step explanation:
27 divided by 3
Answer:
17
Step-by-step explanation:
We are given the expression find x + 9 if x = 8.
When a certain number has a variable and the value of the variable is known, all you have to do is plug in the variable amount into the equation, therefore :
x is 8 , so we plug in 8 for x
x + 9 =
8 + 9 = 17
Well you never sent a picture but the most logical answer is 80 cm
