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).

(2x3)+(3x5)-(3x2)= 2x3=6 3x5=15 3x2=6 So..... 6x25-6= 6x25=150 150+6=156
5+5+5
The generalisation is that multiplication is Abelian (or commutative) for numbers.
2+3*5 = 2 + 15 = 17
3x5+4=19
15/40 = (3x5)/(8x5) = 3/8
r = 3 s = 5 t = 6 rs = 3x5 = 15 rt = 3x6 = 18 st = 5x6 = 30
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.
