Y = x + 2
5x - 4y = -3
Solving systems by equations
1 answer:
Answer: x = 5, y = 7
Step-by-step explanation:
1. First, put the variables together/rearrange:
y - x = 2 & 5x - 4y = -3
2. Cancel out variable x by multiply the first equation by 5:
5y - 5x = 10 & 5x - 4y = -3
3. Add equations:
y = 7
4. Then determine x by plugging y back into the first equation y = x + 2:
x = 5

Answer:
number 1 i already answered that and Im correct
Use pythagorean theorem
c2 = a2+b2
c2 = 16^2 + 12^2
c2 = 256 + 144
c2 = 400
c = 20
The answer is A because -3 + -5 = -8 + POSITIVE 2/3 is -7 1/3
