Answer: Use main properties of powers
to simplify given equation.
1.
2.
3. Then the equation is
The bases are the same, so equate the powers:
2x=-3x-15,
2x+3x=-15,
5x=-15,
x=-3.
Answer: for x=-3.
Step-by-step explanation:
Answer:
40/31
Step-by-step explanation:
4x = (1/8)x + 5
=> 4x - 5 = (1/8)x
=> 8(4x-5) = x
=> 32x - 40 = x
=> 32x - x = 40
=> 31x = 40
=> x = 40/31
