Question

2 by 3 (Y - 5) minus 1 by 4 (Y-2)is equal to 9 by 2​

Answer 1

2/3(y-5)-1/4(y-2)=9/2

cross multiplication

2(2-1)=9[{3(y-5)}-{4y-8}]

4-2=9[{3y-15}-{4y-8}]

2=(27y-135)-(36y-72)

2=27y-135-36y+72

2=-9y-63

9y=-63-2

9y=-65

y=-65/9

hope it helps u

Answer 2

Answer:

$y = 62$

Step-by-step explanation:

$\frac{2}{3} (y - 5) - \frac{1}{4 } (y - 2) = \frac{9}{2} \\ \\ 2y - 10 - y + 2 = \frac{9 \times 3 \times 4}{2} \\ \\ y - 8 = 54 \\ y = 54 + 8 \\ y = 62$
