Solve 12−5x−4kx=y for x.

IgorC [24]

Answer:

x = $\frac{12-y}{4k+5}$

Step-by-step explanation:

12-5x-4kx=y

1. Subtract 12 from both sides.

2.Distrubutive property (factor) a(b+c)=ab+ac

x(-5-4k)=y-12

Divide by -5-4k

x = $\frac{y-12}{-5-4k}$

= $\frac{12-y}{4k+5}$

−15x+4≤109 OR −6x+70>−2

Xelga [282]

$-15x+4\leq109\qquad\text{subtract 4 from both sides}\\\\-15x\leq105\qquad\text{change the signs}\\\\15x\geq-105\qquad\text{divide both sides by 15}\\\\\boxed{x\geq-7}\\or\\-6x+70>-2\qquad\text{subtract 70 from both sides}\\\\-6x>-72\qquad\text{change the signs}\\\\6x$
