Step-by-step explanation:
4 sin (0) - 4
_________
π
12-5=7
21-12=9
x-21=11
21+11=32
x=32
Answer:
x=14
Step-by-step explanation:
45 = 3 (x + 1)
Distribute the 3 to both terms in the parentheses
45 = 3x +3
Subtract 3 from each side
45-3 = 3x+3-3
42 = 3x
Divide each side by 3
42/3 = 3x/3
14 =x
This expression does not have an answer. If both sides are multiplied by 2.6, then you receive an equation of 2.6 = 22.1. Since this expression is incorrect, there is no solution.
Hope this helps!
