Answer:
(-2, 3) 
Step-by-step explanation:
Given the system of equations: 
-3x + 2y = 12
x = 2y - 8 
You can 'substitute' the expression '2y - 8' for the value of 'x' in the first equation and solve for 'y': 
-3(2y - 8) + 2y = 12 
Distribute: -6y + 24 + 2y = 12 
Combine like terms: -4y + 24 = 12 
Subtract 24 from both sides: -4y + 24 - 24 = 12 - 24 or -4y = -12 
Divide both sides by -4: -4y/-4 = -12/-4  or y = 3 
Use y = 3 to solve for 'x': 
x = 2(3) - 8 or 6 - 8 
x = -2

Answer:
2x - 8
Step-by-step explanation:
Product of two and a number x
⇒ 2 multiply by x
⇒ 2x
Eight less than 2x
⇒ Take away 8 from 2x
⇒ 2x - 8

A. X^2-10x. =-8
 To complete the square you get half of -10 and then square that number half of -10 is -5 and -5 times -5 equals positive 25 that would you add to each side
x^2-10x+25=-8+25
