6x+25=16-3x
+3x. +3x
9x + 25= 16
-25. -25
9x=-9
x=-1
3/10 × 10 would be 30/100 which would make it easy to add to 21/100 and that would = 51/100
-5 and 15. -5 times 15 is equal to -75, and they also add to 10.
Answer:
x=2
Step-by-step explanation:
let the unknown number be x
now we are to find x regarding the question as an equation, let's form the equation to solve for x
the interpretation of the question is:
(x² + x)/3 = x
by collecting the like terms:
(x²+ x) = 3x
x² + x = 3x
x² = 3x - x
x² = 2x
x = 2
Step-by-step explanation:
the conjugate is -5-2i
(-5+2i)(-5-2i) =29+0i
a=29 b= 0
