We can do the elimination method to find the solution for this problem. The elimination method involves adding the two equations together to get rid of a like term.
x + 2y = 7
+ x - 2y = -1
—————————
2x = 6
Now that we eliminated 2y because they cancel out, we are left with 2x = 6. Divide both sides by 2 in order to get x.
The answer is: x = 3.
Now that we know the numerical value of x, all we have to do is plug x into either system of equation in order to find the numerical value of y.
x + 2y = 7
3 + 2y = 7
2y = 4
y = 2
The solution to the problem is (3, 2).
12.5 is greater than 1.25
Answer:
the 3rd one.
Step-by-step explanation:
-11 is the smallest number, followed by -1, the numbers are then listed correctly in an increasing order after that.
Answer: 22 miles
Step-by-step explanation:
1/4 times 4 = 1 gallon
if Rob can travel 5 and 1/2 miles on 1/4, then to find how far he can travel on 1 gallon we multiply 51/2 by 4
5 1/2 x 4 = 22
