Ответ:
x = -5
Step-by-step explanation:
8x+32=1/5(25x−15)−4x
8x + 32 = 5x - 3 - 4x
8x + 32 = x - 3
7x = -35
x = -5
Ответ:
x = -5
Step-by-step explanation:
Let's expand the parentheses on the right side first:
(1/5) * (25x - 15) = (1/5) * 25x - (1/5) * 15 = 5x - 3
Now put this back in:
8x + 32 = 5x - 3 - 4x
Move all the x terms to one side and all the constants to one side:
8x - 5x + 4x = -3 - 32
Combine like terms:
7x = -35
Divide both sides by 7:
x = -35/7 = -5
Thus, the answer is -5.
Hope this helps!
