no solution
substitute y = 2x + 4 into the other equation
2x - (2x + 4) = 6 ( distribute and simplify )
2x - 2x - 4 = 6 ( add 4 to both sides )
0 = 10 ← not possible
Hence the system has no solution
Answer:The answer is 48
Step-by-step explanation:
Answer:
0.375 or 3/ -8
Step-by-step explanation:
28 - 8x = 15
- 8x = 15 - 18
- 8x = 3
x = 3 / - 8
x = - o.375 or 3/ -8
I believe the answer is C
Step-by-step explanation:
3√(x - 4) + 7 = -14
3√(x - 4) = -21 (subtract 7 from both sides)
√(x - 4) = -7 (divide 3 on both sides)
However √y is non-negative for all values of y in the domain of √y.
Hence there is no real solution for x.
