Oxana [17]

Answer:

$(A) y=1.5$

$(B)x=\dfrac27$

$(C)x=2\dfrac23$

$(D)x=-5.25$

Step-by-step explanation:

(A)

$3y - 2 = - y + 4\\3y+y=4+2\\4y=6\\y=\dfrac64\\\\y=1.5$

(B)

$5 - 4x = x + 3 + 2x\\5 - 4x = 3 +3x\\5-3=3x+4x\\7x=2\\x=\dfrac27$

(C)

$-12 - 9x = - 4 - 12x\\-9x+12x=-4+12\\3x=8\\x=\dfrac83\\\\x=2\dfrac23$

(D) $- x - 6 + 3x = -2x + 8x + 15$

$2x-6 = 6x + 15\\2x-6x=15+6\\-4x=21\\x=\dfrac{21}{-4} \\\\x=-5.25$

Find the value of Y in the figure above .

Blizzard [7]

9514 1404 393

Answer:

x = 37
y = 22

Step-by-step explanation:

Consecutive interior angles are supplementary.

(x -20)° +(4x +15)° = 180°

5x = 185 . . . . . . . . . . . . . . divide by °, add 5

x = 37 . . . . . . . . . . . . divide by 5

74° +(5y -4)° = 180°

5y = 110 . . . . . . . . . . . divide by °, subtract 70

y = 22 . . . . . . . . . . divide by 5
