50*x=80 (x=percent in decimal form)
x=1.6 (divide both sides by 50)
Doubke check:
50*1.6=80
80=80
Convert 1.6 into a percent:
1.6 -> 160%
Set up a system of equations:
B=2+3C
B+C=90
The variable B is already solved, so plug into bottom equation:
2+3C+C=90
2+4C=90
4C=88
C=22
Plug C back in:
B+22=90
B=68
So B is 68 degrees and C is 22 degrees
Hope this helped!
So, if we need to find 1 factor, let's just multiply 13 × 2.
13 x 2 = 26.
So, 26 is your answer.
Glad I could help, and good luck!

Answer:
The method used is substitution method
x = 2, y = -6
Step-by-step explanation:
Given the simultaneous equation
Y = −3x ..... 1
4x + y = 2 ... 2
Substitute equation 1 into 2
4x + (-3x) = 2
4x - 3x = 2
x = 2
Get y:
y = -3x
y = -3(2)
y = -6
<em>Hence the value of (x, y) is (2, -6)</em>
