Answer:

x= 0 and x = -4

Step-by-step explanation:

The first step for absolute value equations is to isolate the expression contained within the absolute value bars:

3|2 x+4|-1 = 11

3|2 x+4| = 12

|2 x+4| = 4

So |2 x+4| is 4 units away from 0 on a number line, but we don't know in which direction -- negative or positive? you'll have two answers.

2 x+4 = 4

AND

2 x+4 = -4

Solve both of those two step equations and you'll get

So 0 and -4 are your solutions

garri49 [273]

Let's solve your equation step-by-step.0.2(x+50)−6=0.4(3x+20)Step 1: Simplify both sides of the equation.0.2(x+50)−6=0.4(3x+20)(0.2)(x)+(0.2)(50)+−6=(0.4)(3x)+(0.4)(20)(Distribute)0.2x+10+−6=1.2x+8(0.2x)+(10+−6)=1.2x+8(Combine Like Terms)0.2x+4=1.2x+80.2x+4=1.2x+8Step 2: Subtract 1.2x from both sides.0.2x+4−1.2x=1.2x+8−1.2x−1x+4=8Step 3: Subtract 4 from both sides.−1x+4−4=8−4−1x=4Step 4: Divide both sides by -1.−1x−1=4−1x=−4Answer:x=−4
