15y+14=2(5y+6)
15y+14=10y+12
15y+14-14=10y+12-14
15y=10y-2
15y-10y=10y-2-10y
5y=-2
y=-2/5
-3
x/5y + 2x/3y = 3x/15y + 10x/15y = 13x/15y
If x = -7, then x3 = -343 so that 2x3 = -686 y = 2 then 15 y = 30 So 2x3 + 15y = -686 + 30 = -656
Y=55y-3=2y+123y-3=123y=15y=5
No.
-3
Multiply the first equation by 3 to give 9x + 15y = 21
x/5y + 2x/3y = 3x/15y + 10x/15y = 13x/15y
i have no clue what the answer is
.225
3y plus 6x = 2
Combine like terms, meaning add 12X plus 4X which is 16X and then you add 25Y plus 15Y which equals 40Y so the answer will be 16x+40y. combine like terms means add the ones with the same variable.
If x = -7, then x3 = -343 so that 2x3 = -686 y = 2 then 15 y = 30 So 2x3 + 15y = -686 + 30 = -656
Y=55y-3=2y+123y-3=123y=15y=5
No.
3xy-4x + 15y-20 Sol: As there are no number are same. So -4x-3xy +15y-20 -------------------- -4x-3xy+15y-20
The slope is 1/3 and the y-intercept is -1.
