How do you solve 3.2(6x-7.2) = 0?
2 Answers
Explanation:
- Apply distributive property
a(b+c)=a(b)+a(c)
3.2(\color(crimson)(6x)\color(orchid)(-7.2))=0 becomes...
3.2(\color(crimson)(6x))+3.2(\color(orchid)(-7.2))=0 - Simplify by multiplication
\color(crimson)(19.2x)+(\color(orchid)(-23.04))=0
19.2x-23.04=0 - Isolate the term with variable
x using addition
19.2x\cancel(-23.04)\cancel(color(tomato)(+23.04))=0\color(tomato)(+23.04)
19.2x=23.04 - Isolate the variable
x by division
(\cancel(19.2)x)/(\cancel(\color(lightcoral)(19.2)))=23.04/(\color(lightcoral)(19.2) - Here is your result!
x=1.2
