y = x - 3
y = 3x - 5
Since the two expressions on the right are both equal to 'y', they're equal to each other.
x - 3 = 3x - 5
Subtract 'x' from each side:
-3 = 2x - 5
Add 5 to each side:
2 = 2x
Divide each side by 2:
x = 1
Return to the first original equation, and substitute (1) in place of 'x':
y = x - 3
y = 1 - 3 = -2
The point where the two lines intersect is (1, -2).

The generalisation is that multiplication is Abelian (or commutative) for numbers.
3x5+4=19
Commutivity of multiplication or the commutative property of multiplication.

(2x3)+(3x5)-(3x2)= 2x3=6 3x5=15 3x2=6 So..... 6x25-6= 6x25=150 150+6=156

The generalisation is that multiplication is Abelian (or commutative) for numbers.
3x5+4=19
2+3*5 = 2 + 15 = 17
15/40 = (3x5)/(8x5) = 3/8
r = 3 s = 5 t = 6 rs = 3x5 = 15 rt = 3x6 = 18 st = 5x6 = 30
No, a 3x5 matrix cannot be multiplied by another 3x5 matrix. For matrix multiplication to be possible, the number of columns in the first matrix must equal the number of rows in the second matrix. Since a 3x5 matrix has 5 columns and the second 3x5 matrix has 3 rows, multiplication is not defined in this case.
Ah, what a happy little question! The inverse operation of multiplication is division, so to find the inverse of 3x5 equals 15, you would divide 15 by 5 to get 3. Remember, math is like painting a beautiful landscape - just follow the steps with a gentle touch and you'll create something wonderful.
