Step-by-step explanation:

\frac{4x}{x}  =  \frac{48}{(x + 2)}  \\ 4 =  \frac{48}{(x + 2)} \\ 48 = 4(x   + 2) \\ 48 = 4x + 8 \\ 48 - 8 = 4x \\ 40 = 4 x \\  \frac{40}{4}  =  \frac{4x}{4}  \\  = x = 10

If 5a=-4b+5 and 3a=-2b+3, what is 6b?
never [62]
<span>Simplifying 3a + -2b = 5a + 6b Solving 3a + -2b = 5a + 6b Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add '-5a' to each side of the equation. 3a + -5a + -2b = 5a + -5a + 6b Combine like terms: 3a + -5a = -2a -2a + -2b = 5a + -5a + 6b Combine like terms: 5a + -5a = 0 -2a + -2b = 0 + 6b -2a + -2b = 6b Add '2b' to each side of the equation. -2a + -2b + 2b = 6b + 2b Combine like terms: -2b + 2b = 0 -2a + 0 = 6b + 2b -2a = 6b + 2b Combine like terms: 6b + 2b = 8b -2a = 8b Divide each side by '-2'. a = -4b Simplifying a = -4b</span>
