Answer:
X=3
Y=1
Step-by-step explanation:
In solving simultaneous equations, there are three methods, we have the elimination method, substitution method or graphical method. But for the purpose of this question, we would be using Elimination method.
5y-4x =-7 Equation 1
2y+4x=14 Equation 2
Since x has the same coefficient, it's easy to eliminate by adding up the two equations
5y+2y=7y
-4x+(+4x)=0
-7+(+14)=7
We have 7y=7
Divide both sides by 7,
y=7/7
y=1
Substituting for y in equation 2.
2(1)+4x=14
2+4x=14
4x=14-2
4x=12
x=12/4
x= 3
3.2 . I don't really know how to explain this, but I need to write at least 20 characters to give you my answer.
Answer:
building a aroung 50.34 feet
If x is the smaller one, and is odd, the next consecutive odd integer is x+2.
Check:
11(13) = 143
23 + 5(11 + 13) = 23 + 120 = 143, check
-3(-1) = 3
23 + 5(-3 + -1) = 3, check
Answer: 11,13 or -3,-1
