<span>y = –2x + 5
–5y = 10x + 20
replace </span>y = –2x + 5 into –5y = 10x + 20
–5( –2x + 5 ) = 10x + 20
10x - 25 = 10x + 20
-25 = 20...can't be...

Answer:
x =
Step-by-step explanation:
Solve for x:
- x² + x² = 1²
- 2x² = 1
- x² = 1/2
- x = √(1/2)
- x = (√1)(√2)
Rationalize the denominator
Elminate the radical
- x = (√1 * √2)(√2 * √2) ⇒ Rationalize the denominator
- x = (√2)/(2)
