Ok, so the square root of x is the same thing as saying x to the power of 1/2. So you make your roots into exponents.
2(x^1/2) + 20 = 15 + 3(x^1/2)
The answer is d, its 25
Answer:
D- No solution
Step-by-step explanation:
Isolate x for x+2y−z=3: x=3−2y+z
then Simplify
then Isolate y for −5y+4z+6=6: y= 4z 5 −5y+4z+6=6 Subtract 6 from both sides −5y+4z+6−6=6−6 Simplify −5y+4z=0 Subtract 4z from both sides −5y+4z−4z=0−4z Simplify −5y=−4z Divide both sides by −5 −5y −5 = −4z −5 Simplify y= 4z 5
lastly simply.
