the answer is x=1. This is how I worked it out
5x-3=2
2+3=5
5 divide 5 = 1
If you're asking what x equals, it equals 5 because 5x3=15, and 15-2=13.
The generalisation is that multiplication is Abelian (or commutative) for numbers.
3x+5=20 x=5 since 5x3+5=20
5x3 - 3x2 + 2x = x*(5x2 - 3x + 2) The quadratic has no real factors.
y = 5x3 + 6 is a cubic equation, not a linear equation. Linear equations contain only terms of degree 0 (i.e. constants) and terms of degree 1.
If you're asking what x equals, it equals 5 because 5x3=15, and 15-2=13.
5x3=15 is the inverse
5x3=4 2x8=2 6x3=3 1x7=7/40
The generalisation is that multiplication is Abelian (or commutative) for numbers.
Commutivity of multiplication or the commutative property of multiplication.
5x3 = 45x Divide both sides by 5: x3 = 9x Divide both sides by x: x2 = 9 Square root both sides: x = 3
Since 5x is a factor of both terms, divide it. 5x3 + 5x = 5x(x2 + 1)
3x+5=20 x=5 since 5x3+5=20
look its one of the easiest questions I've ever heard 5x3 is 15 for god sake anybody who dosent know that there one of the dummest person in the world!

2(10x6) 4(5x3)
