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
