Answer:
(2, 1)
Step-by-step explanation:
To solve by substitution, we solve one equation for one of its variables and then substitute the solved value for that variable into the other equation. Because this system of equations already has one solved for the variable, this makes our job much easier. We only need to implement the solved value for y into the other equation and solve for x.
y = 6x - 11
-2x - 3(6x - 11) = -7 Distribute.
-2x - 18x + 33 = -7 Combine like terms.
-20x + 33 = -7 Subtract 33 from both sides of the equation.
-20x = -40 Divide by -20 on both sides of the equation.
x = 2
Then, with this value, we will place it into the equation that was already solved for y in order to get a definite value for y.
y = 6(2) - 11
y = 12 - 11
y = 1
Using this information, the coordinate pair for this equation (the point of intersection between the two lines) is (2, 1).
Hello there.
Question: Find two square numbers that have a sum of 130
Answer: Use trial and error:
It would be 81 + 49 = 130.
Hope This Helps You!
Good Luck Studying ^-^
It’s 2 because you plug in “x+1” as y into the the first equation then solve for x.
That is known when there is no like terms to be added, and for the case of a fractional function: there is no more common factors between the numerator and the denominator.
Hope that help
