Answer: x=7
Step-by-step explanation:
Step 1: Subtract 17x from both sides.
13x+15−17x=17x−13−17x
−4x+15=−13
Step 2: Subtract 15 from both sides.
−4x+15−15=−13−15
−4x=−28
Step 3: Divide both sides by -4.
−4x/−4 =−28/−4
x=7
Answer:
x=pi*n/2+1/2arctan(7/5)
Step-by-step explanation:
5sin(2x)=7cos(2x)
5tan(2x)=7/5
2x=pi*n+arctan(7/5)
x=pi*n/2+1/2arctan(7/5) for n e Z
1,2,3,5,6,10,15,30 because by looking at the number at the ones place, when it is 0 or an odd number, it could be divided by 2. When the places are added together and when it is divisible by 3, it is the factor of 3. Also, when there are 2 and 3 as a factor, it is also divisible by 6.
