Answer: 2
Step-by-step explanation: Fist solve the first problem. -3u-1=2. That simplifies to -3u=3. Now divide each side by -3. Now you should have u=-1. Now put it in the other problem. 2(-1)+4. 2*-1 is -2. So -2+4=2
Answer:
-2/7
Step-by-step explanation:
solve for x so -12+ 8 = 30x - 16x so -4 = 14x so x = -4/14, so x = -2/7
Answer:
Step-by-step explanaAnswer:
\frac{-2y+5x}{3x-2y}
Step-by-step explanation:
Given:
\frac{\frac{-2}{x}+\frac{5}{y}}{\frac{3}{y}-\frac{2}{x}}
To simplify this expression, first make the addition and the subtraction, to get:
\frac{\frac{-2y+5x}{xy}}{\frac{3x-2y}{xy}}=
Next, simplify the two denominators, to get:
\frac{-2y+5x}{3x-2y}tion:
