6y + 5y = -66 11y = -66 (-66/11 = y) y = -6
6y=5y+2y 6y=7y that does't work its unequal -
5x + 6y + 3y - 2x you have to add like terms. add the y terms and then the x terms 9y + 3x this is your answer
(A) x + 6y = 19 (B) -x + 6y = 17 (A)+(B): 12y = 36 so that y = 3 Substituting this value of y in (A), x + 18 = 19 so x = 1.

10y= 6y+5+3y 10y=6+9y y=6
6y + 5y = -66 11y = -66 (-66/11 = y) y = -6
6y=5y+2y 6y=7y that does't work its unequal -
5x + 6y + 3y - 2x you have to add like terms. add the y terms and then the x terms 9y + 3x this is your answer
x=6y-4x=-2y+28Substitute (6y-4) for x in the second equation and solve for y:6y-4=-2y+288y=32y=4Then solve for x:x=6(4)-4=20(20,4)
y-3x+6y=12 7y=3x+12 y=3x/7 +12/7
(A) x + 6y = 19 (B) -x + 6y = 17 (A)+(B): 12y = 36 so that y = 3 Substituting this value of y in (A), x + 18 = 19 so x = 1.
Not sure if you mean 7x 6y as in 7*6y=126, where * means "multiplied by" and you must solve for y or if you mean that we must solve for both x and y, but the answer to the part where you are solving 7*6y=126 is 3.

3x + 6y + 6x = 9x + 6y which can be factorised as 3(3x +2y)
4x+6y=62 -6x+6y=-18 what is the ordered pair
6y = 12x+32 Divide all terms by 6: y = 2x+5 and 1/3 which is now in slope intercept form
