Answer:
x=12
Step-by-step explanation:
(8x-20)+(8x+8)=180
16x-12=180
16x=180+12
16x=192
x=12
There is no algebraic way of isolating X unfortunately.
For these equations, you have to solve with numerical approximation.
I suggest Newtons method if you know calculus.
Answer:
22/35
Step-by-step explanation:
first get a common denominator in order to add. The common denominator is 35.
the new fractions should be 7/35 + 15/35
