2X - 3 = 13
add 3 to each side
2X = 16
divide both sides by 2
X = 8
check
2(8) - 3 = 13
13 = 13
checks
(2x3)+(3x5)-(3x2)= 2x3=6 3x5=15 3x2=6 So..... 6x25-6= 6x25=150 150+6=156
First, you would add 13+13, which equals 26. Then you would subtract 26-13 which equals 13. So the problem would be 26-13=13.
13
It is: 4 times 13 equals 52
12 x 13 = 156
2x3 + 4 = 17 2x3 = 13 x3 = 13 / 2 x = (13 / 2)1/3 x = 521/3 / 2
13
4 equals 2x2, 6 equals 2x3
Not necessarily.
If x = -7, then x3 = -343 so that 2x3 = -686 y = 2 then 15 y = 30 So 2x3 + 15y = -686 + 30 = -656
The multiples of 6 are: 6x1 and 2x3.
(2x3)+(3x5)-(3x2)= 2x3=6 3x5=15 3x2=6 So..... 6x25-6= 6x25=150 150+6=156
your equation is this... 2x3 + 11x = 6x 2x3 + 5x = 0 x(2x2 + 5) = 0 x = 0 and (5/2)i and -(5/2)i
5-2x3=9
13
x = -7, y = 2 ⇒ 2x3 + 15y = 2 x (-7)3 + 15 x 2 = 2 x (-343) + 15 x 2 = -656
4+4+4and 6+6+0 and 2x3+6
