5x - 3 = 22
add three to both sides
5x = 25
divide both sides by 5
x = 5
The generalisation is that multiplication is Abelian (or commutative) for numbers.
If you're asking what x equals, it equals 5 because 5x3=15, and 15-2=13.
3x+5=20 x=5 since 5x3+5=20
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.
Because the answer to 5x0.5 is 2.5 as the answer to 5x0.3 is 1.5 and 5x3 is 15.

Commutivity of multiplication or the commutative property of multiplication.
Since 5x is a factor of both terms, divide it. 5x3 + 5x = 5x(x2 + 1)
5x3 = 45x Divide both sides by 5: x3 = 9x Divide both sides by x: x2 = 9 Square root both sides: x = 3
3x+5=20 x=5 since 5x3+5=20
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.
In the expression 5x3 equals 15, 5 represents the number of groups or sets, 3 represents the number of items in each group, and 15 represents the total number of items when the groups are combined.
Because the answer to 5x0.5 is 2.5 as the answer to 5x0.3 is 1.5 and 5x3 is 15.
No. x=3. (5x3 is 15 or 5x =15-3=12)
3x4 plus 5x3 plus x2 - 5 divided by x 2 =[(3x4) + (5x3) + (x2 - 5)]/x2 =(12 + 15 + x2 -5)/x2 =(27 - 5 + x2)/x2 =(22 + x2)/x2
x + 3 = 6xx - x + 3 = 6x - x3 = 5x3/5 = 5x/53/5 = x
