Answer:
I believe the answer is X=2.5
Step-by-step explanation:
7+2=9
so now we have to find what X would be so we can do the second equation
So we know that the second equation must equal 6 because 9+6=15
So now we experiment with different numbers for X
if we did 2, the new equation would be 2x2+1 which is 5, too low
if we did 3, the new equation would be 2x3+1 which is 7, too high
So we need something in the middle
in the middle of 5 and 7 is 6 which is the number we need
so to get 6 we need something in between 2 and 3, which in 2.5
hope this helped!
Answer:
(-18, -3)
Step-by-step explanation:
To solve this system of equations, use the substitution method.
Steps for substitution method:
Step 1 : First, solve one linear equation for y in terms of x.
Step 2: Then substitute that expression for y in the other linear equation. You'll get an equation in x.
Step 3: Solve this, and you have the x -coordinate of the intersection.
Step 4: Then plug in x to either equation to find the corresponding y -coordinate.
